OK, I was using the RC, then I had this problem and decided to try the beta (it was a 1.5 beta only).
Thanks for the firewall help, I checked (and rechecked and rechecked and rec...) but it was all ticked (looked like it wasn't that).
drrag, running as admin -just- showed the black screen, the loading bar didn't appear.
Zenobia, thanks for that! I've corrected the shortcut (I can't remember if it was mine or SB's..)
I did set the SB shortcuts already existing to run as admin, but how it moved from spybot to SDMain I don't know!
As above, do/did have a 1.5 spybot, was showing hidden and system files, but didn't know about there was -another- system files option in vista! have now seen the file and it seems to be running now, hope it'll work after!
