Can't join my Tekkit server

[SkidGreenWarrior]

I made a Tekkit 2.1.1 server but I can't join it with the tekkit launcher, I can't even find 2.1.1 on there. Can anyone help? The server is working but I can't log in it just says "Internal Exception: blah blah blah"

Incorrect format, with no useful information given, and an error message condensed to the point it could be one of countless things. You can't be helped if you don't give much information past "it doesn't work".

OK, make sure you have java 7 installed, I would tell you whether to get 32 bit or 64 bit but since you didn't follow the bug format I have no idea what OS you are using. In the launcher use the drop down in the top left to make sure TEKKIT is selected, not technic. Then click on the options button in the bottom right of the launcher and make sure you have recommended build selected NOT development build. If it's still not working then update your (pretty useless) post to the bug format so we know what OS, tekkit versions etc you are using and someone can help. Also say if it's a hosted server or your own PC, are you using hamachi, if it's your own PC is the the same PC or a different over a LAN etc.
