I checked in the cache cleaning (or what is that), so it cleaned its settings, and also I did mess with AppData, (I think) I deleted every kind of file after uninstall which is in connection with Vegas.
The next day I’ll look for that file you mentioned, and will make sure that it’s deleted.
I’ll take a look at deleting AppData, but I’m not sure I’m gonna do that.
Thanks for your help.
