Installation Problems.Follow

I recently bought the game, the one including the original and the expansion, and I fully downloaded it and everything but whenever I choose a server an error message pops up says something along the lines of the lotroclient.exe not being found and the game client passing invalid command-line parameters.

I have uninstalled and reinstalled three times, changing the location of the save just to see if that was it, and I have yet to get anything. If anybody could help me figure this out so I could try this game out it would be very much appreciated.

Edited for typos.
