Thank you for your reply..
But unfortunately it didn't work.. I submitted a bug tho

I've been doing some more research on this. And two more items come up in the searches. The 1st is anti-virus software. You may want to put in an exclusion for the FTB/Curse folders to prevent live scanning of those files. The second has to do with adding mods to the pack. Did you add any? If so make a backup of our world then try to remove them just to see if the game loads.

 

[SwimBiggs24]

well, that's the thing I didn't modify my modpack or have an antivirus on my PC... plus I downloaded infinity and it is working fine!

That's why it's kinda driving me nuts!

 

[Henry Link]

Ok... So the log you posted isn't very helpful. Can you open the pack directly and pastebin the latest.log file from the logs folder?

Looks like something is wrong with my minecraft forge, although i deleted the whole thing and re-downloaded it!

I fixed it, thank you for your support Henry.

What I did was went to curse-->FTB unstable 1.10 profile-->opened "..."--->Profile Options--->changed current modloader version to the newest version

=> something was blocking earlier version of the forge. It's really weird especially if you don't have antivirus
