This thread is for someone who knows Java quite well, like kukelekuuk00 or JamieSinn I tried reinstalling my usual mods, as 1.5 came out. As usual, I installed Minecraft Forge first. I opened Minecraft to see if it works. It doesn't, it comes up with an FML error (This is with ONLY Forge installed, nothing else). The mods I use are: - OptiFine - Rei's Minimap - Macro Mod / Liteloader - InvTweaks - Not Enough Items If someone can please help me with this, I'd really love it. I use Minecraft forge Universal 7.7.0.608 as it says that's OptiFine is compatible with.
Go to .minecraft and copy the contents of ForgeModLoader-client-0.log Paste it in quote or code tags in a new post.
