Title explains it. I was playing FTB and shut it down for an hour or two. I reopened it and the launcher said there was a new update :)

Installed the update and now when I attempt to open Ultimate, I get the following message:

Could not find the main class. Program will exit/

I've tried about 5 times to open and I get the same result...

Check if the FTB-Folder has Spaces or other uncommon characters in it...
I had it installed in "C:\FTB Mods", after renaming it to "FTBMods" it worked for me... I had the same problem that it couldn't find the mainclass and it's working now.

I have the same problem I clicked update and the launcher closed but the console stayed up and displayed the same text as the post above I've tried closing the console and then opening the launcher again and just the console appeared and displayed the text from the post above although mine says FTBLaunch starting up (version 1.2.9) instead of FTBLaunch starting up (version 1.2.8)
