Forums are perfectly fine for chatting, though keep in mind your issues have nothing to do with the converter itself. If you can run the conversion, the mod is fine.
Doing conversions on their computers will produce different mods, don't do that.
Editing dessriptor.mod is pointless, descriptor.mod does nothing. Instead, if they copied your mod, they need to edit the .mod file one folder above. The file is probably called r2d3.mod. Inside edit the path to match their systems exactly.
Only do this if they are using the manual - copying method. If they have BOTH the manual mod (mod they copied from you) and the SAME mod they subscribed to through steam, they won't get anything running! Do one or the other!
