I'm sure ya'll are taking bets on if this one has been rehashed before already but I've been looking for 30 minutes and have yet to find a corresponding thread.
1. Installed Java 7 64 bit and 32 bit.
2. Downloaded Ender's client
3. Double click to run
Black screen
Error: Can not find or load main class C:\ whatever path it is to the jnpl.
Any assistance would be greatly appreciated. It's been nearly two years since I last terrorized Haven.
