Launcher/pack Version:It says it is Tekkit 3.0.0 Operating System: XP Version of Java: Don't know, sorry. Description of Problem: I use the developement builds of tekkit and it says that tekkit can update to the version for 1.2.5 (3.0.0). But whenever I try and load tekkit, it just gives me a white screen and doesn't close the launcher. (Don't know whether this is relevant, but I open the launcher with the .jar because the .exe doesn't work on my computer). Error Messages: N/A
