Not able to open existing documents in InDesign due to 'missing plug-ins'

I am no longer able to open documents I created a few months ago in InDesign. An error message flashes up to say that it is 'missing plug-ins'. However, I can still create new documents. I have tried uninstalling and reinstalling the software but the problem still persists.

I am a relatively new Mac/InDesign user so would appreciate it if you could talk me through step by step.

Thanks!

If you uninstalled/installed the software, then you must have overlooked reinstalling the plugins. You need to determine what the plugins are that you are missing and reinstall them.

OK, I reread your message. Please answer the following and we can hopefully figure this out together.:
First, why did you reinstall it a few months back?
Second, do you know what plugins you have and where they are located? (ie disk, download, etc.)
Third, did the error message tell you which plugins were missing?

Hi BongSoo

Apologies for the late reply. Here's some further information for you which will hopefully clarify the situation:

- I have this problem only when opening old files (ie ones I created earlier this year) and ones that have been sent to me externally - and yes all these files are in the same version of InDesign that I use - CS2. Strangely I can open recent files no problem and I am able to use InDesign to create new files.

- This is what happens when I try and open one of the affected files: Firstly a dialog box pops up with the warning symbol and the following message 'Missing Plug-ins - lists LILO.InDesignPlugin, CellStyles.vpln.InDesignPlugin. The document x uses one or more plug-ins which are not currently available on your system. Do you want to open anyway?' So I click okay and get a further dialog box which lists 20-30 or so missing plug-ins starting with AppFramework.framework, Table Model.framework, InCopyShared.framework and so on. It goes on to say 'Can not open x. Please upgrade your plug-ins to their latest versions, or upgrade to the latest version of Adobe InDesign

- I tried re-installing the software to see if it would rectify this problem but with no joy. The InDesign plug-ins folder appears to be located in the InDesign application folder in my Applications folder if that helps.

Sorry I'm just getting used to working on a mac again after many years and am not very up to speed with things technically. Hope to hear from you again soon.

If you do a reinstall, you have to make sure you go through and delete EVERYTHING related to the software in question. If you are using on of the Creative Suites, you have to DELETE EVERYTHING, and then REINSTALL EVERYTHING.
Most likely this is the problem. I would try deleting all files - be methodical - every file must be hunted down and trashed.  Then reinstall the whole suite.

Hi BongSoo

I have re-installed the whole creative suite but unfortunately the problem persists. I believe I was pretty thorough in deleting each and every Adobe related file. Any other suggestions? Getting a bit worried about this now.

Thank you

Honestly, I think it comes down to one of two things:
1) Something wasn't deleted
2) Something wasn't reinstalled
I'm afraid I can't tell you which one is the problem, but I am reasonably certain this is the case.

Apologies for the long absence. I eventually came to the conclusion that I was trying to open files that had been created in CS3 (even though the icon indicated they were CS2) as I had free CS3 download trial software around the time the problem files were created. Recently an agency sent me a file saved as .inx (I think that's it anyway) and I had no problems opening it. I am also able to open recent files which were definitely created in CS2. Thanks anyway, fingers crossed that's it.
