Unrecognizable database format

What is the full name and path of the database file and how are you trying to access it?  Are you opening Access and then trying to open the database file or are you double-clicking on the database file?
What version of Access are you using?
What version of Access did the database come from?

I think the picture did not attach that showed the error or at least it doesn't show on my phone.   The pic showed the entire path.  I am away from the computer at the moment but will be back in 30 min.  

I am using 2010.  I was passing the file between two computers: 1 with 2010 and other I think 2013 (whichever is the next latest version after 2010).  The file was fully developed though but I added contacts here and there but no modifications from what I can remember.  I am not using the other computer now tho and now I get the error.

Let me know what is next

It was initially developed in 2007 and was contacts DB template.  I have been using it in 2010 and 2013 without any issues until I stopped using the 2013 computer.

OK here is the complete path:

C:\Users\pdvsa\Documents\Personal\Computer\contact list management

<Are you opening Access and then trying to open the database file or are you double-clicking on the database file?
==>I tried it both ways.

Can you show the exact error you're getting?

You might try a Decompile. Make a backup, then create and run a Shortcut with this as the Target:

"full path to msaccess.exe" "full path to your db" /decompile

After decompiling, try to Compact - Compile - Compact again.

If those don't work, it's possible you have a corrupt Form or Report. Try importing your objects one-by-one into a new, blank database. If you have one that's corrupt, Access will alert you when you try to import it. If so, you could import everything else, and then restore the trouble object from a known good backup.

You can also try the SaveAsText/LoadFromText method listed here:

If none of those work, you're probably left with a recovery service, like www.everythingaccess.com.

Scott,

Thank you.
Question:
<You can also try the SaveAsText/LoadFromText method listed here:
<https://www.experts-exchange.com/questions/28450832/SaveAsText-all-forms-or-objects.html

Is the SaveAsText method to be used from within the corrupted db or do I run it from the immediate window from within another blank db?  

I tried the decompile method before posting this question.  I received the same error.  
I can open up a backup though but it is not current.

here is the error:

Also, is the "CurrentProject.Path" suppose to be the path to the file or do I leave as is?
SaveAsText acForm, "Contacts", CurrentProject.Path & "\ Contacts.txt"

Ok thank you.  Since I can not open the corrupted DB nor import any objects not compile it seems like my only option is a data recovery service as you mentioned.

There were format compatibility problems between 2007 and 2010.  See my Access Archon article on this topic, which discusses various approaches to fixing the problem:
