I have TMPGEnc Authoring Works 4, and suddenly like a week ago, it stopped working, every time I tried to run it, it gave me this error

EAcccessViolation occurred – module
TMPGEncAuthoringWorks4Batch.exe / 6D63AB69
At address 6D63AB69 , read error occurred against address 6D63AB69.

I have reinstalled it, deleted it from the registry, upgraded, everything I can think of. What is wrong?
