Hi all,

I'm running into this error message when I try to use MagicLauncher to run Minecraft with the Plenty O' Biomes mod:

I have watched a number of videos on how to use the launcher with 1.6.2, and I've installed Forge and am choosing that environment in the settings. The launcher sees the .jar file that I've downloaded and it shows 'ok' as the status. But when I try to launch or just run 'test', that's what I get, the lower chunk of the text above. I don't have the launcher and the .jar file in the same directory but that doesn't help either, and I've navigated to the .jar file anyway so it shouldn't matter where it's specifically located. Be that as it may, I now have it in the .minecraft/mods folder that appeared after installing Forge, and get the same error.

Has anyone else seen this and hopefully know how to fix it?

Thanks.

I'm having the same problem.. I've made sure magic launcher is set to use the 1.6.2 environment, but it doesn't help.

If my upgrade procedure may reveal some mistakes:
1. I downloaded the new launcher from mojang and updated to 1.6.2 using that first.
2. Then I got the new magic launcher, and ran that.
3. I downloaded the new version of optifine (that's the only mod i use).
4. I clicked Setup, changed the environment to 1.6.2, and used 'Replace' to upgrade to Optifine_1.6.2_HD_U_B4

When I press Test or try to run minecraft normally through magiclauncher, I get the same error:

Any help is appreciated (as long as it's not 'don't use magiclauncher' or something equally non-productive).
