> Xcc mixer.exe and mix eitor.exe both wont work on my computer, they did the other day but when i downloaded 1.21 they all stopped opening, when i click the exe it says 'xcc mixer has caused an error in xccmixer.exe, if you continue to experience problems please restart'
> I restart and the same message shows up.

Delete "global mix cache.dat" and "standard file list.dat".
