There are plenty of threads about this in the technical help forum. Search there.

Even though there are several other threads explaining this, I'll say it again.D2 uses a new save type, which none of the current flashcarts on the market can use. Because of this, it gives that error message.There is a patch that fixes this. http://forum.romulation.net/index.php?topic=41140.0
