Here is all the info provided with the crash:
Application Failure ultradefrag.exe 126.96.36.199 in ntdll.dll 5.1.2600.5512 at offset 000109f9
We are already investigating the ntdll.dll crash issues.
Here is another crash report, Windows XP SP3, 32 bit, if this helps.
Application Failure ultradefrag.exe 188.8.131.52 in ntdll.dll 5.1.2600.6055 at offset 000101b3
Sorry for the late reply.
I have been tracked aside by real live issues.
We are currently working on resolving the issue.
