War 3 Image Extractor

I'm using Paintshop Pro, and I'm done skinning my design. When I use the War 3 Image Extrator to try to convert the file into a *blp, I get this message saying that that file has an unsupported compression. Now, I saved it as an uncompressed file in Paintshop Pro, and I redid the skin twice, and still get the same message. It's probably something stupid that I'm doing wrong...but if anyone knows what's wrong, please tell me. Thanks in advance.

I know other people must have this problem and it's not addressed in the tutorials. Can someone please just offer a suggestion?

Are you using PSP 8? For some reason, it doesn't work with version 8.

Really? Never knew it was that...thanks for the help. Guess I'll have to download yet another demo, lol.

You can convert it back with WC3 Viewer, I got same problem with PSP8, didn't know it was because of PSP 8 until now though...
