So I install forge mod loader to minecraft, everything was good, but when I add mods to the mod folder in .minecraft, it says "we think your system may be modded" or something like that,  it won't let the launcher run, I supposed this was to do with the META-INF folder,  but when I try to delete that, FML gives me a "CRITICAL TAMPERING WITH MINECRAFT" HA? no shit, that's the whole point of forge mod loader, right?. I already tried manually installing mods to the jar but that doesn't work with or without FML.  anybody got any feedback or experience? manual fml/mod installing was so much easier before. and yes I'm a newb modder. 

 

p.s. congratulations on being stupid as hell.

Do NOT edit the jar.

 

Forge has an installer, use it.

I tried using the installer, as I said. re-read the post.

Would have responded sooner had I been at my PC, anyway...

 

Your post does not mention the installer, and sounds very much like you tried the old way,

but lest skip that and get to problem solving.

 

 

I figured I'd give the new launcher and Forge Installer a go (hadn't yet used either)

So starting from a clean .minecraft folder (never used it, was using multimc)

I ran the Forge installer (build 789) it failed of course but I wasn't sure if it installed everything or not so I figured I try it

Into the Minecraft launcher, created a new 1.6.2 profile and ran it once.

I ran the Forge installer.

Opened the Minecraft folder and dropped my freshly compiled mod in

Launched the profile,

Everything worked

 

 

So for your problem, try cleaning out the .minecraft folder and start fresh.

If that doesn't work try one mod at a time, one must be causing the problem.

thanks. but I did try using the 1.6.2 installer. still gave me a "we think your system has been modded" and refuses to run. ill try clean again some other time but for now I guess ill be using older forges. the old way was so much more reliable.

BTW this is not the place for help installing. For help go here.
