try this i had same problem as you....
Unistall BS make sure everything is unistalled, included any folders,
Then go to Run, Type regedit, then click on EDIT, Find, And do a search for anything to do with black shark, ie type blackshark search, delete anything
that comes up, Press F3 to keep searching, then install game again, and you should be good to go, it worked for me:thumbup:
