Acrobat Now Crashes When Appending with Scanner

Question

I have Acrobat 9.3.3 installed and everything worked great until all of a sudden it now crashes almost every time I try to append to a document with scanning in additinal pages.  As well as it'll crash from time to time when I do a "Save As".  The crashes seemed to start after I installed a Wacom Bamboo tablet.  But I'm not sure how that can effect it.
My system is Win 7 64bit, scanner is a Canon DR-2580C using the same driver as always.
I've reinsalled Acrobat completly and my scanner driver but the crashing is still there.  It seems to be fine when I scan in the first batch of docs to a new file, but then I can't append to a doc with more without crashing.
After installing the Wacom tablet, Acrobat poped up with a wizzard for doing Accessibility options (which I don't want) so I went back into preferences and unchecked everything under accessibility.  And still crashing.
Below is what my event viewer shows for the last Acrobat crash:
Event 1000, Application Error
Faulting application name: Acrobat.exe, version: 9.3.3.177, time stamp: 0x4c1d77c5

Not sure what the deal is.  I'll try removing the wacom tablet but it's something I need to have now.
Thanks!

Problem Solved!  I removed the Accessibility.api plugin from Acrobat and now my scanner and Acrobat is back to working normal with no crashes.  AND with my Wacom tablet installed and running.  So something about the accessibility screen reader part and the Wacom tablet don't like each other.
I disabled the accessibility option plugin as this other member posted:
"If you are trying to disable a plug-in the preferred method is to crate a new subdirectory under the Acrobat application, like "optional" or "disabled" and move the api plug-in file you want to disable to that folder. This keeps the name and extension standard and easily allows one to renable the API. But this process has to be done to each user's system and does not allow selectively turning it on or off. "
