Sims 3 game launcher troubles - please help!

[gabirpower]

Hi!
I recently reformated my computer and decided to start fresh with all my sims 3 games.
After downloading them all, I went to the exchange but found that when I clicked download, it would not go through to the game launcher.

Even after saving the individual files and opening them in the launcher, when I try to install it tells me my game is not up to date despite this bein innacurate. 
Any suggestions as to what I should do?
Thanks mileyhappy:
