superantispyware (not responding)

I have posted about having spyware on my computer and was told to go to a friends computer and download free superantispyware onto a cd. The next step was to go to safe mode on my pc and insert the cd. I made sure that the cd contained all the data.When I went to run the program in (safe mode) it said this edition has encountered a problem and needs to close. I tried running it out of safe mode and received the same screen. what next?
