hmmm I just tested this at my work computer and I get the same error as before.
I have no idea what could be wrong. Maybe it's because of mng format? Maybe the trouble with that format? Because flx_extractor works perfectly with no errors at all and crusader2mng keeps not converting the spr files. Maybe it's better to convert directly to animated gif? Maybe the problem with this mng format? Not sure, just an idea.
Heh... but still very great work RPGMan, you are da best bro!!! I wish we had a programmer like you for our Crusader: No Hope 3D. We have a banch of designers, modellers, a writer and a musician here, but not a single programmer rofl.
