Glad it was working for you.

To fix this:
Press Windows Key + R
That opens a run prompt.
Paste
%temp%\low\arcadeox
Press enter.
That opens the arcadeox temp folder.

If you delete all the zip files in that folder and inside the storage folder, then it should fix any problem. You can delete anything in that folder but your save states and custome settings are in there as well.

Also rebooting would probably fix it.
