Ax 2009 client is closing on import xpo

Dear All,

While importing classes from V 3.0 to Ax 2009, AX client is closing and giving error message like this “Microsoft Dynamics AX client has encountered a problem and needs to close. We are sorry for the inconvenience.”

But in eventviewer error message is "

Faulting application ax32.exe, version 5.0.1500.1313, stamp 4ab4246b, faulting module kernel32.dll, version 5.2.3790.4480, stamp 49c51f06, debug? 0, fault address 0x0002237e."

I did not understand anything from this error message and now I’m not able to proceed further. Please helm!!!

Thanx,

Ambanna Yatnal
