i use mcp a lot of years without problems, but from wbstartup and not ss. if you follow the instractions on which patches of mcp NOT to use if you have some other patches in your us or/and ss you will not have problems. delete or rename temporary the prefs file of mcp, boot and if it goes ok then run the mcp prefs and set the functions you want to use. personaly i always install/update mcp manualy.
