I purchased the Mach3 tutorial cd instead of downloading it on my slow dial up service. It has been very helpful so far. I am having trouble with some of the videos. They seem to in fast forward and are garbled also are very small and hard to read. Others play just fine. I sorry but I don't know which ones they are right now but I can get that info for you if needed. Thanks for your help.

Your best bet is to go to the site that you purchased it from and email from there.
