Details of the issue:

I just updated from 1.3.1 and the game just will not launch, has some sort of error in the log but I don't understand any of that so I've included the log. When I downgrade back to 1.3.1, everything works fine. Missing the game a little so if anyone can help me out with what's wrong that'd be great lol​

Please post a full log and upgrade your java.

Ok I updated java and it still does not launch. I am not sure which file is the "full log" that I should post?

 

[jikuja]

In the launcher's options tab, check the boxes "Show Console" and "Reopen launcher when Minecraft exits". Then launch your pack again and when

the crash/error/other problem occurs, click the "post log to pastebin.com" or "upload log" button and give us the link.

I feel so observant, I've never noticed you could click it right there in the console to pastebin. Thanks for your patience with me lol

On the launcher go to options then click the force update button, then launch the modpack.

After trying what you last suggested, the game still would not launch. I decided to try fully uninstalling JAVA as well as fully deleting FTB. (Which I had tried earlier but I didn't realize there was also a folder in appdata.... ) so after deleting them both fully and reinstalling the game seems to launch fine so I wonder if the issue was related to java needing to be updated? There were 3 listed in my control panel so maybe there was a conflict with that. All I know is it is working now lol
