All, 
  There has been some maintenance on LIM (XMIM, MIM etc.). So, if you are using excel addin please follow the below instructions. 
1. Reboot the (your) machine 
2. Run Start -> Programs -> Business applications -> LIM -> Xmim Excel User (installation)
  After these steps you should be able to use the lim, mim etc. This should work. If it doesn't you can contact me
Thanks
