I read your directions and even though that is exactly what I tried last time.. I tried it again .. and it worked
Now, I will try another little 'drop in'.. too scared to try the big ones lol
thank you
later:
Successfully installed 2 more but then removed one to replace it with another (group mod) and the old one continues to show up.
The only thing I did differently that I can see was that you said to d/l install etc and then close out the game. I always closed out the game totally before I even did the d/l. But whatever, it is working now
