None of the things work: no skin (nor the option to clear anything there), no boosted sound, no cxmb (i guess, still unsure what this does;-)).
I'll search for some more answers today.
Cheers.
edit; the path to cxmb was wrong as it was misplaced in the seplugins folder. I guess it works now. Can i see if the volume boost now works?
Anything else i can do with cxmb, like checking (hidden) files so i can get rid of the 6.37 crap?
