Minecraft Forums

I was playing Minecraft and feed the beast just fine but then i re-downloaded java-64 and now when i open Minecraft it says " The registry refers to a nonexistent java run time environment installation or the run time is corrupted and the system cannot find the path specified". AN d when I open feed the beast it says " Adobe reader could not open FTB_launcer.jar because it is either not a supported file type or because the file has been damaged". I really would appreciate some help to try to get back to my games.
