I have .net 3.5 + sp1 and SQLDigger works fine, although it's possible that I installed it before I had that framework installed. I just confirmed that SQLdigger is functioning OK though. May be worth a try. You could also try searching syscomments for the user, but if you do that, some sprocs will span multiple records in that view so the username could be split in 2 if that makes sense, but it's worth a try as well.
