Resubbed, activated it in Rimpy and it loaded just fine. Cheers mate, thanks for the mod.

So far I haven't been able to reproduce the problem, but I did find an error in the capitalization of the tag for the package ID, which uniquely identifies the mod. I have fixed that now. Possibly it will resolve your issue. If not, can you see any error messages that look relevant? (If you turn on developer mode, the game will show you an error log on start-up and also when opening your mod list.)

I can't get this mod to activate for some reason. I have used Rimpy and Fluffy's mod manager but on every restart it's in the inactive list.
