Stopped processing files

[kb2ur]

purchased 4.005 two days ago. I had a set of 20 cd-g.zip backed up on external hard drive. The first 13 processed without errors and was able to move to play list and also write to disc.

After that all files had total errors when processing.

I then selectes Write to disk and selected files to import.
This worked for the next set. After that I kept receiving import errors.

I tried other compressed files from my internal hard drive and cd's and still get the same errors.

I have all updates on my pc.Cleaned registry. defraged hard drive ect. looked through the forums. Can't seem to find a reson for it to stop working.

I can process files from cd-g cd's and duplicate disk.
