Hi SwordFish,

Try this tool and see if it does anything:

http://www.sarc.com/avcenter/venc/da...oval.tool.html

then http://registryrepair.1found.com/

There are some more here:

http://www.handyarchive.com/free/registry-repair/

Be sure to back up the Registry before you do anything with it

Hopefully that will eliminate the possibility of Blaster remnants, and anything weird in the registry.

You might like to get it to happen then run HijackThis and post the log?

Good Luck
