Thunderbird mail will not open

[hciclos]

Thunderbird was bringing in an email when I terminated everything. 
Thunderbird will not open.
Just flashes on screen.   
I uninstalled Thunderbird, reinstalled it.  No luck.

Obtained another ntdll.dll, not quite the same as mine in system32.
It will not go into systen32 anyway.

Any help is appreciated...........

System Restore?

[hciclos]

Thanks for response.
Sorry, forgot to mention 'System Restore' is the first I tried.
Did not cure the problem of opening Thunderbird. 

[Broni]

1. Uninstall Thunderbird.
2. Delete the Thunderbird program directory.
3. Reboot.
4. Disable Firewall.
5. Disable Anti-virus.
6. Install Thunderbird.
7. Re-enable Anti-virus.
8. Re-enable Firewall.
9. Launch Thunderbird.
10. Report back the results.

Hi Broni,
Did everything listed above.
Launching Thunderbird results in only it flashing then disappearing to give that same box--'Mozilla Quality Feedback Agent'.

The Thunderbird 'Safe Mode' given in 'Programs' only flashes also, and will not open.
Even downloaded another full Thunderbird version--2.0.0.22--from Mozilla.
Does same, no launching.

Does ntdll.dll in System32 corrupt?
Please see event log above.
I have another extracted from my WinXP-Pro CD.
Of course, it will not let me replace the one in System32.

Restart computer in Safe Mode. Rename existing file to ntdll.old, and paste new one.

Broni,
Thanks.

The new extracted ntdll.dll was placed in my System32 as per your instructions.
Thumderbird still does not launch.
I discovered that 'Guest User' and creating another new 'User'--that it does launch.

So is there something in my User appl.data under 'Thunderbird', or in the registry regarding a 'Thunderbird key" that prohibits launching?  Even restored the system back to last month, and there was no correction of the problem.

I also tried eliminating that 'Talkback' which does launch everytime I try launching Thunderbird.  No Luck there.

Let's redo.
I forgot, TB creates another folder, so...
Uninstall TB.
Remove TB folder in Program Files, and TB folder in C:\Documents & Settings\<your name> \ Application Data
Restart computer, and try to install fresh copy.
