I haven't been able to play minecraft for over 2 months now, so I would really like a fix, each time I recieve the following error:

Please fix the error and restart.


I've tried reinstalling Java, deleting .minecraft, I don'tknow what else to do, or what is causing this. Please help if you can.

Remove all traces of Java from the machine. Reboot, then grab the latest 64-bit version here,

How would say I go about removing all traces?

First, go to the Programs and Features in Control Panel (Add and Remove Programs on XP). Uninstall everything that says Java in the name.

Alright, anything else?

That is it, now follow the rest of the instructions.

Wow, it actually ended up working even though I've tried uninstalling it before, thanks a ton for your help!
