Reactor planner issues

double click the jar (standalone)

maybe try a diffrent browser

you got the right java for your system?
when you have 64bit you need the 64 bit version.
also try the java runtime envrioment

Reactor planner issues

Hey, I have a problem, that it isn´t loading... i tried reinstalling java, and IE as well as FF, nothing worked.

I got the standalone version but don´t know how to use it. Any suggestions or ideas?

Thanks

If you're using firefox, you need to make sure to install the 32-bit version of java. The 64-bit does not work in Firefox. You can have both the 64-bit and 32-bit versions of java installed at the same time in case you still want to play minecraft with the 64-bit version of Java.

At a guess, your broswer may be insisting to use version 1.6 of Java. Assuming you've not tried that already.
