Launcher/pack Version: Just updated 22-04-2012 to 0.5.4.9 Operating System: Windows 7 64bit Version of Java: Latest Java 7 Description of Problem: After your press Login on launcher it launches 2nd window for tekkit but only shows white screen, tried waiting 15minutes still only white screen, have tried to clear the cache and redownload, didnt help, launching with recommended build it works but we can't play on our multiplayer server with this, we are a group of people playing this server all with this problem. Error Messages: White screen Link to pastebin of log: http://pastebin.com/70aywymw Edit: Looked over the sticky threads and saw this mentioned **The launcher freezes on a white screen when I log in. Sometimes the lwjgl (Light Weight Java Games Library) binaries just don't work for everyone. Disable lwjgl by opening the launcher and clicking "Options" above the log in field. Then uncheck "Use latest LWJGL binaries". The latest LWJGL binaries option wasn't/isn't on and I am still getting a white screen. Might be time to post a bug/problem report. But first, try going to .techniclauncher\<modpack name>\bin and open the jinput.jar. (on a mac you may have to rename the .jar to .zip and extract it, then rezip and rename to a .jar after you're done.) Delete Meta-INF. If that doesn't work nuke the .techniclauncher folder and re-download it.** Done it, No longer get white screen but it opens my normal minecraft instead of Tekkit.
