I cant join a tekkit classic Server <:(

[Higa]

When i opened up the launcher and went to tekkit classic it opened up the start menu page, i use the Bdcraft texture pack for tekkit, and basically i try to join one of the servers that are on these forums and ith said all that stuff about downloading the terrain and simulating the world for a bit and all that in the loading screen and then it all was done and then it said nothing and then it showed the crash screen for a second and then went white. I get to many problems just to start this mod
