Black screen opening wemod

Hi, before i had no issue with the software, but nopw when i try to open it, only a black screen appears. I tried installing again, and it worked, but now I have the same issue. Can anybody help?

Any recent changes?

Do a clean install, delete these folders
C:\Users%username%\AppData\Local\WeMod
and
C:\Users%username%\AppData\Roaming\WeMod

Then uninstall
