Lync Client won't Start

Question

Hi,
Had a weird issue the other day where as the Lync 2010 Client would not start. I had not received any updates, but it gets to signing in and then crashes.
I've removed it and removed the Microsoft Visual 2008 C++ that comes with it and reinstalled it but I still get the error:
Microsoft Lync 2010 has stopped working - A problem caused the program to stop working correctly....
When I debug it through Visual Studio, I get:
Unhandled exception at 0x771af482 (ntdll.dll) in communicator.exe: 0xC0000005: Access violation reading location 0x00000004.
In the Windows Event Log I get the following:
Faulting application name: Communicator.exe, version: 4.0.7577.0, time stamp: 0x4cc15778
Faulting module name: ntdll.dll, version: 6.1.7601.17514, time stamp: 0x4ce7b96e
Exception code: 0xc0000005
Fault offset: 0x0005f482
Faulting process id: 0x10fc
Faulting application start time: 0x01cd3415238cd8c2
Faulting application path: C:\Program Files\Microsoft Lync\Communicator.exe
Faulting module path: C:\Windows\SYSTEM32\ntdll.dll
Report Id: 8f958e12-a00b-11e1-8b46-a4badbeed198
Any ideas anyone?

Hi,Paul,
Have you tried to log on another Windows account and see if s/he can start the Lync client?
Would you please delete the sip profile folder for this user on the computer and try again?The Sip folder path is like below
C:\Users\username\AppData\Local\Microsoft\Communicator\[email protected]
Hope this helps.
