When dialing into the state from a billing software to verify patient eligibility information I get "A Fatal Exception OE has occurred at 0028:C0275C87 in VXD VWIN32(04) + 00003E63". I can dial 2 times into the system just fine but on the third time I always get this error message. I then have to reboot in order to be able to dial again. This started happening after doing an upgrade to the software. The funny thing is that I have several machines running the same software and it only happens on one machine. The modem seems to stop responding after the error until I reboot the PC. Any suggestions will be appreciated.

Access to an illegal instruction has been encountered or Invalid data or code has been accessed or The privilege level of an operation is invalid.
When any of these cases occurs, the processor returns an exception to the operating system, which inturn is handled as a fatal exception error. In many cases the exception is non-recoverable and the system must either be restarted or shut down, depending upon the severity of the error.
04: Overflow Trap
The overflow trap occurs after an INTO instruction has executed and the 0F bit is set to 1.
Run regedit, search for VWIN32. Set the START bit to 00.
