A softmod runs by changing files on your C drive, if you then use Slayers it almost always formats the C drive and reinstalls the MS dash which overwrites your softmod files on the C drive, causing the softmod to be deleted, also Slayers will install Evox to either C, F, or G, but your softmod may be searching for E:\Dashboard for evox so agian, it wont boot evox. Slayers is only to be used for Chipped/TSOP'ed Xbox's. Download the LATEST versions of the apps you want from the usual place, then install them manually to your softmodded xbox.
