Trying to use my second download

[dancagle]

After reading another thread about having to load an earlier version before loading 4.08, I tried to do this and 3.21 would not allow my authorization code to go through, the original code was lined out and a new one was given that matched the code for the 4.08 download. I could download 4.08 using the code given, but then I had the problem with the d: drive showing as bad and unable to read a cdg disk. Could this be because I was unable to download the 3.21 version?
