Well I'm not sure what the issue is, nobody else has reported to me this problem with my skin.
That error message must mean that my .inc files are not being loaded in, so maybe make sure that 5 .inc files are in the skin folder.
Or even to really force it to work, copy all of the code from "full.inc" into one of the .ini files in the "Full" folder replacing the line "@Include=Full.inc" then try load that up.
