The download window pops up and says it needs to be opened with an application.  It highlights "C:\Program Files\Curse\CurseClient.exe"-url"%1" in the window, but it won't download.  Is there another application I have to download to make it work?  My program files doesn't have that app in there.  I know it sounds dumb, but it really is an issue.  Any help would be greatly appreciated.

Well if you dont have thwe Cuse Client insatlled on your computer, then you have to clcik the download manually button. is this your problem?
