I got the newest 1.7,10 version but when I launch the game it says the core is needed even when its installed, how do I fix this?

Redownload?

Tried, nothing.

It could be that some of your ProjectRed .jars are different versions, make sure they are all the same. Otherwise, please provide the FML log in <minecraft>/logs/fml-client-latest.log (as a pastebin or similar)

I got them all from the site and they all say 4.5.0.50

Okay, can we have the logs? Something's up.

The latest client please :)
Should be in the path I stated above.

you want the lasted or client?

you want all, the lists pretty long.

Yes, put in pastebin / paste.ee or any other paste service

Here you go

And little side note, I'm using the 4.5.0.49 version for now. So it'll say stuff about that most likely.

I think that's why I couldn't find anything wrong in the log in a glance.
Could you use 4.5.0.50 and post the log after launching that version

k hold on

Here this if from my testing pack that has the same problem

Your ProjectRed-Base-1.7.10-4.5.0.50.jar is definitely corrupt. You need to re-download it
FML states:
Unable to read the jar file ProjectRed-Base-1.7.10-4.5.0.50.jar - ignoring

I'll try again

Worked this time but weird the first of second didn't install, I got them all from here: http://projectredwiki.com/wiki/Version_archive
