Where exactly is the crash report? In the main folder for FTB itself I see a FTB Launcher Log and a Minecraft Log. I'll post those two but if they arent the crash report then tell me please
EDIT: forgot to mention i've been getting a crash now that says this:
Based on your crash report, one or more of a few things could be going on here:
1. Your Minecraft files are corrupt or have been moved - redownload
2. Your Forge files are corrupt - redownload
3. You have invalid Java parameters - go to Advanced Options and clear the Additional Java Parameters field
4. Your Minecraft client is cracked - don't do that
