Apparently using hash symbol (#) in skin folder names can cause problems when using official launcher from Kunos (thanks @chrisi2174 for the info). So removed the symbol from folder names.
If you're like me and use Content Manager only this update is not necessary.
You can also remove the symbols (#) yourself.
If you download and install this update anyways remove the previous version.
Sorry for the inconvenience. This should be the final version.
