I was having issues downloading the mods for the ultimate FTB pack (the client was launching as vanilla mc) so I went to re download the client thinking that might help. Though when I click on the download link on the FTB homepage (links to http://www.creeperrepo.net/direct/FTB2/18606e7928709218bd2a4386fb84ada9/launcher^FTB_Launcher.exe) I just get a very basic web page saying "The system cannot find the file specified."
