Before you try to upload a program, its good practice to download the program first. Not only is it good to keep an un-molested copy of your tune, you can't mess up your PCM by downloading. You can however, mess things up during a failed upload. Make sure the key is in the "run" position and you have the correct COM port selected in Tunercat, as well as the correct PCM definition file. Once you can download a file, you should be able to upload one.

Try searching in the computer/diagnostics section and you might find some leads.

You could try the DOS version of the flash/read programs. Its safer IMO than windows b/c DOS is so simple and no other programs run at the same time. Tunercat will send them if you ask but you need a special boot disk with XP as it doesnt have DOS... just PM me if you need that. Hope that helps.

are you trying to run Datamaster and Tunercat at the same time?

Only one program can be using your COM port at a time.
