Windows XP SP 3 - Blackberry Desktop Manager 6.0.2 Will Not Open

Question

When I try to start the desktop manager software I immediately get the windows message: "BlackBerry Desktop Software has encountered a problem and needs to close.  We are sorry for the inconvenience."  I've consulted many resources and tried several fixes, including taking ownership of the registry, renaming one of the library files, and downloading a .NET patch, so far no luck.  Any help would be appreciated.

Answer 1

Got it to work.
Here is what I did:
I took the advice to call Verizon.  Verizon obviously couldn't help, because it is a software issue, not a phone related issue.  After getting passed around to two Verizon Tech Support people, the last one connected me to RIM tech support and handed me off.  The first person at RIM asked VERY basic questions and didn't know what to do with this issue, so they connected me to the next level up.  The RIM tech support had me uninstall/reinstall DTM 6.0.2 and rerun, I think he was trying to get a recent event logged that would detail the problem.  Incidently, he asked about any security programs that might be running in the back ground and suggested shutting everything off.  After the uninstall/reinstall, the program still crashed before it started up and we got the familiar windows "Blackberry Desktop Software has encountered a problem and needs to close...". 
At this point we went to the system log by going to "Run" in the start menu and typing %temp%.  There are two logs I emailed blackberry Tech Support: BB_Desktop and BB_DM.  We also looked at the event viewer in computer management by right clicking My Computer, selecting "manage", expanding "event viewer", selecting "application".  We looked at the errors associated with the software crashing.
Here is what we learned:
It wasn't a blackberry software issue, but a microsoft .NET framework issue (which I had read about and thought I tried an update in some other threads about this issue, but clearly didn't carry the ball far enough).
At this point, blackberry Tech Support told me to contact microsoft to help fix the problem.
Rather than spending another 3 hours on the phone, I decided to try to repair/update the .NET framework on my own.  After several downloads and updates, the blackberry software now works like it should.
These are the resources I used, in order.
1. Download the "Full Redistributable Package" of .NET Framework 3.5 full package near the bottom of the page of http://www.microsoft.com/downloads/en/details.aspx?FamilyId=333325fd-ae52-4e35-b531-508d977d32a6&dis...
2.  Uninstall using Add/Remove Programs all previous Microsoft .NET Framework programs (there were 3)
3.  Install the "Full Redistributable Packge downloaded in #1 above.
4.  Downloaded and Installed Microsoft .NET Framework 4 (Web Installer) from http://www.microsoft.com/downloads/en/details.aspx?displaylang=en&FamilyID=9cfb2d51-5ff4-4491-b0e5-b...
5.  Navigated to Microsoft Update at http://www.update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us and selected Express update
Several of these steps required a reboot, etc.  I just followed all of the instructions.  Of course I kept checking and hoping the blackberry desktop software would work.  It finally did after #5 above--the express update found I needed to install some high-prioirity update that I can only assume was a patch or something to the.NET framework.
In any event, the whole thing took about 45 minutes and now the desktop software is functioning.
To any real computer people who may evaluate all of these steps, I'm sure I have some redundancies, but whether or not this was the most eloquent way to solve the problem, it got me to the finish line.
If your issue is a .NET framework issue, this could help solve your issue.
Good luck
