System Upgrade kills CDAudioplayer

I have a PowerMac 6100/60 w/ 16mb RAM and internal Apple CD 300i Plus.  Everything worked fined until several months ago when I upgraded the Mac OS 7.5.1 which came with the CPU when I bought it in 1995 to 7.5.3.  Now the AppleCD Audioplayer version 2.1 no longer works!  When I attempt to play a CD, I get a dialogue box that says the disc is unreconizable and then asks if I want to eject or intialize it.  What happened?

Also, an old (1990) version of Microsoft Word (which I use to read old files) no longer works.  I get some dialogue box saying something about an application error.  I tried reloading the program and still get the same box.  This application worked fine before I upgraded.  (To read old files, I have to drag out my old SE!

Please help!  How can I adjust the upgrade?

Open up your Extensions folder. (you can't use extensions manager because they won't show up there) Check to see if the extensions "Audio CD Access" and "Foreign File Access" are in there.  If not, this is the cause of your problem.  You need to put them in the Extensions folder.
What version of Word do you have? If it's 6.0, make sure you get 6.0.1a.

I think you need to try a few things.

First, go to Apple Menu | Control Panels | Extensions Manager. Save the current set to, say, "Susan Set 1." After saving, choose the System 7.5.3 only set, close, then restart.

Everything but the Mac OS extensions are now turned off. Does your 300i CD ROM work now? If it does, you have some extension conflicts to sort through. If that is the case, please submit a comment. If no, then...

Is your CD ROM getting power? (Do you see a power light, or do the disks spin up when you insert a CD?) No, then you may may have a loose power connection or a bad CD. Please submit a comment if that is the case.

If the CD is getting power, then you may have some corrupted system files which you need to replace. Depending on how your Mac OS and updates were installed, this could be a rather straightforward process.

If you need help replacing the system files, submit a comment with information on your original OS installation software, and the upgrades you've installed. (OS 7.5 unavailable, on floppies, or on CD, Updates on CD or downloaded from net and still available, etc.)

Thanks, Dolly!  I turned on all the extensions and the CD Player and Microsoft Word work just fine.  Actually I got this answer from someone in a Newsgroup, but thank you for answering anyway.  I've also upgraded to 7.5.5  All systems are go!
