Intuit Statement Writer (ISW) Fatal Error

When I try to start Intuit Statement Writer (ISW) or want to generate a report in ISW, I get the following error message:
Unable to open statement: System.AccessViolationException:
Attempted to read or write protected memory. This is often an
indication that other memory is corrupt.
Server stack trace:
Exception rethrown at [0]:

I really need your help to solve this.
Thanks!
