@FayFen the last version of VEGAS that DLL script would work in is 13. Do you have a newer version for Magix versions of VEGAS?
What did that script do?
As it's compiled, I assume you got it from somewhere else. Where did it come from?
In searching, it appears it may be part of Happy Otter Scripts. I would recommend you download the current version that supports MAGIX versions and reinstall.
