Was there a newer version of the software available than the one you currently use?
I still have a very early version of SidTool, already version 1.0, but still an RC, which was released in February. The guy began coding the tool in January, so until today I'm pretty sure there are some more releases.

The guy is also on the AEP emulation board, as he presented his tool there, perhaps I'll send him a PM.
