When I add a mod using jsgme, I always watch out for a message at the top "not responding".
This happens a lot with large mods. (MO OH II)
When I see this happen - I reject the mod.
Then try it again, until it loads without the "not responding".
You should try Sobers mod list.
He has been at this a long time and tests every one.
