If you are upgrading, it's a good idea to backup your old installation by copying it somewhere safe... (At least backup your /SCRIPT and /KEYS directories).
This version:
Fixes some Win7 compatibility issues, and added some Win7 specific error trapping.
Removes realtime unpacker from the EXE (which was tripping off some virus scanners with false-positives).
Other minor bugs fixed, cosmetic adjustments.
Please advise if you have any issues, and I'll get them resolved asap. Thanks!
