Reader XI won't open docs

Question

Was just forced to "upgrade" to Reader XI, now I it won't open any of my docs.
When clicking on a document, Reader opens, but not the document, then about 2-seconds later Reader XI closes itself.
I uninstalled it, then reinstalled it, same thing.
Tried docs stored on my hard drive, and some that was on my email server, doesn't matter.
I tried opening the reader from Start->Programs, but it refuses to start that way.
X- version worked great, now it's gone.
Machine is a Toshiba Satellite, I-7, 32-bit Windows-7.

Hi,
I ran into this same problem and was able to solve the problem. 
I'm using a laptop with NVIDIA video card and discovered that the NVIDIA Video Driver was somehow conflicting with Adobe Reader XI's  EULA.exe program, which runs first time after install.
Problem:  As Adobe Reader's  EULA.exe ('End User Licence Agreement') never runs, you can never 'Agree to Terms and Conditions' of use, and Adobe XI shuts down, thinking you have 'Not agreed' to terms of use.
I had to go into Windows "Event Viewer" (Application Log View) to see that EULA.exe was "faulting" with the NVidia video driver.  Error message will look something like this:
Faulting application name: Eula.exe, version: 11.0.0.379, time stamp: 0x505fc5b0
Faulting application path: C:\Program Files (x86)\Adobe\Reader 11.0\Reader\Eula.exe
Faulting module path: C:\Program Files (x86)\NVIDIA Corporation\CoProcManager\nvdxgiwrap.dll 
Anyway, "the fix":
I needed to install latest NVidia video driver to resolve this problem.  Earlier in March (2013), Microsoft released a number of "Optional" Window 7 Hardware Driver updates.  Among them was NVidia Video driver.  After I installed the Microsoft recommended NVidia driver, Adobe Reader X (and Adobe Reader XI) both ran fine.    ie:  The 'End User Licence Agreement' (EULA.exe) now runs the first time after install, I now say "Yes", "I accept the terms" and Adobe Reader XI runs fine. 
This is the first time I've ever seen a Video driver cause a conflict with Adobe.
The easiest way to check for this update, Click on:  Start --> All Programs --> Windows Update.  
Then Click on "Optional Updates" and see if NVidia Video driver is among the recommended driver updates.   If "Yes", select it (click on check box), install it, reboot, and see whether this fixes the problem.     
Alternately, go into Windows "Event Viewer" --> "Windows Logs" --> "Application",   and see whether there are any "Errors" (Red !'s) listed immediately after running Adobe Reader.   
If you see an Error message reading something to the nature of:
Faulting application name   Eula.exe       ....and the name of the other application Adobe's EULA.exe is 'faulting' with,
check to see if you can download & install an update for the other problem application (or driver) causing the fault with EULA.exe,  in the hope this fixes the problem.
Anyway, my own experiences with this one.
