Bump.
The add-on no longer works due to Blockland, or more precisely the new launcher, automatically overwriting changed default files.
Instead of replacing the files directly, I suggest that you make the add-on read them from a .zip file in the add-ons directory. This would also make it easier to manage skins outside of Blockland.
Also, since you apparently have managed to get your hands on a copy of profiles.cs, why not allow people to supply their own custom files? This way people can change stuff such as fonts and GUI element behaviour. You might be forced to do this since paths will be screwed up otherwise.
