ok this is my stats now...
codechikencore match notenoughitems mod
lunatrius match schematica
the mod pack version is 1.8 matching the modpack.jar
and it still wont open
edit: optifine 1.8.1 was in the mod, i changed it to 1.8 to see if that'll work
Edit 2:
It works!!!!
what i did was i removed the coremods folder (as it was empty)... i did also have to remake the modpack on the technic site as it refused to update the download link but it is all good now! thank you so much for you help!!
