Using Win7 I was having a lot of crashes without any apparent cause or pattern. Tried everything and couldn't get it to be reliable enough to flash, crashed twice while flashing and got 2 corrupted PCMs (fixed them already but still a hassle).
Then I emailed both Moates and Tunercats about the issue, I was told the tuner program was not designed to run in Windows 7 or newer, I was advised to use a Virtual XP Machine to avoid crashes since it was a known issue and there was no ETA for a fix. I did it and haven't had a problem since.
