I can not update JMonkeyEngineSDK

Hi, guys.
I can not update JMonkeyEngineSDK
When I update and restart IDE, I again offer to upgrade (all the same update)
What to do?
reinstall did not help.
P.S. sorry for English, i use tranlator

Maybe its not the same updates. Or your install is messed up (installed with admin rghts or something).
