Another annoying help message :)

Hey guys,

As the title suggests, I'm failing at installing FTB! I've followed the instructions on the YouTube post (http://www.youtube.com/watch?v=ax8I_kMwqWI&feature=plcp) and tried both doing it with and without MultiMC. With MultiMC gets me furthest, and it leaves me with an error message of:

\Desktop" MultiMCLauncher "C:\Users\Mark\Desktop\instances\FTB\.minecraft" "Jemima20" -150308987266237572

Are there any people out there who can help? Sorry for being such a pain and failing at following the simplest of instructions!

Cheers

Is there anyone who can help? I've been watching YouTube playthroughs of FTB and would love to try it myself, so any help at all would be hugely appreciated! Thanks in advance

Better then deleting, post how you fixed, so that others who need help someday with the same thing can find the solution there?
