I have the galactic science modpack installed, and a few other mods. But when i try to launch ex compressum with them, it crashes. Can anyone help?

Here's the crash report.

Description: There was a severe problem during mod loading that has caused the game to fail

you need to uninstall ec compressum it crashes is you look at it you see it is UE notUC like others the only fix I know is to uninstall it I don't if there is another way

Are you saying that i need to reinstall ex compressum?I have it sitting out of my mods folder, and everything runs fine, but if i put it in my mods folder, it crashes.
