EAccess Violation in Module TMPGEncVMW5.exe

On starting the TMPGEnc program, I am receiving "Application error: EAccessViolation in module TMPGEncVMW5.exe/689E99E9. Reading error occurred in address 689EA9E9 at address 689EA9E9.” followed by "FastMM has detected a GetMem call after FastMM was uninstalled." The Task Manager shows that TMPGEncVMW5.exe uses almost 100% of the CPU. I have tried reinstalling the program. But it didn’t help resolve the issue. Please help.
