CoD2 jump map errors (Help)

[Legion]

Hello everyone, I recently got CoD2 and I wanted to obviously play CJ anyway, I launch COD2MP_s,then I launch the codjumper mod, then I do "/map mapname", but When the map loading screen is about to finish it says "iwd sum/name mismatch" what can I do to stop this problem from occurring? If you could please tell me I'll love you forever. (this error has occurred with every map I've downloaded)

The usual cause for this is you have to many conflicting iwds in your mod folder but since this is CoD2 I guess they're all in main. Try running one map at a time. Move all other iwds to a separate folder while you play each map.

Also next time try using the search feature: iwd sum name mismatch search.
