Maybe you could provide us with the exact error message.
I start with a fresh Backtrack 4 R2 VM install and use fasttrack to update itself (menu 1, sub-menu 1). When I use Option 4 Microsoft SQL Tools, Option 3 SQLPwnage, nothing happens (I stay on the menu). Options 1 and 2 work ok. Fasttrack menu says its at 4.0.1. Any ideas? Before the update SQLPwnge complains about missing components.
