I don't think this has anything to do with Eclipse/Epic. My guess is you installed something on your PC that installed an older version of the DLL(s). There are several approaches to fix this. I think the simplest(?) is to put your script and all DLL(s) it uses in the same directory. Also, there are tools available to find out exactly what processes (if any) are loading the DLL if you want to investigate. It might even turn out that no other process uses the DLL, i.e. only installed! Did I say DLL-Hell:)

Cheers,
