Registax "failed to decompress error"

I know this topic has been discussed before, but my question was never directly addressed...

I am in the process of my first attempt at Mars with a ToUcam pro and Registax software. When I select the Mars .avi file I get the message "failed to decompress." Next time, I won't use VRecord to capture the file. For this time, though, I need to save my video of Mars! Is there any kind of freeware program that I could use to maybe discard the first few frames or to recompress the file or something?

Any help would be much appreciated.

I had same problem and received a link to a beta version that fix the same problem after using the "report problems by email" tab. That beta version may be the current supplied, so if it's been a couple of weeks since you downloaded the version 2, download and reinstall, may be a later version than you have. If you then have the same problem, I'd then use the "report problems" tab.
