[mod_IC2AdvancedMachines : Unsupported major.minor version 51.0]

@Secret

Your post helped me, I'll help you.

Open your client, hit the options button, choose "Select Build Manually" or something like that, and choose the latest build.

Should fix.

Thanks, broski.

[mod_IC2AdvancedMachines : Unsupported major.minor version 51.0]

I've updated to Java 1.7 using the Windows x86 download (I'm running Vista on a 64-bit, I assumed this was the correct installation as when I install programs, they go to Program Filesx86), but when launching the server, I still get this error:

[Advanced Machines Not Loading (Java 1.7 Installed)]

Launcher/pack Version:2.1.1

Operating System:Windows 7 64-bit

Version of Java:1.7

Description of Problem: Upon starting my server, the command prompt opens, begins initializing as before (I'd used 2.0), then once it gets around to loading the Advanced Machines mod, it shits itself.

Error Messages: Like, a bajillion.
