Something happened last night. I uninstalled SS1.5, removed every sony folder and almost every sony related entry in the registry. After that I installed SS1.5 again. Guess what, it was working once again. A minor problem now is that SS is crashing everytime I try to playback imported files. Nothing to worry about, I only need the damn software to import music and transfer the files to the MD. One last thing. What are those windows media format files? The SS1.5 CD has a folder with those files. I installed everything but SS.3.3 keeps asking for them. Anyway, thanks to everybody.
