Feed The Beast Multiplayer Error

[nXs]

I was playing on the same server before, it worked perfectly then I updated my Feed The Beast and tried to connect and this error came up in my console:

Does anybody know how to fix this?

Please do not bump threads less than a day old. Are you sure the server is online and that others are able to connect? If so please follow the basic troubleshooting guide and then post a full console log to pastebin.com and link to it here for us to try to help.

I've followed all of basic trouble shooting guides and here is my pastebin http://pastebin.com/6MFus982 Thank you for your help so far.

Are you still unable to connect? I no longer see that error in the log. The only one I see is a warning about Myrathi's mod, switches, but I believe that would not prevent you from joining. Also I'm not sure how to remove the switches mod as it does not seem to appear as an individual mod in the list unless it goes by another name and I am not seeing it. Sorry.

I tried opening it again to see if I was mistaken and now this error appears. http://tinypic.com/view.php?pic=jtv1jd&s=5

Are you sure you used the correct version of the pack? That error is common with using the incorrect version.

I'm using v1.1.7 of ftb unleashed, I'm pretty sure that's the correct version.

You might want to ask as the official change log site shows that they may have updated certian mods, but left others as the old versions. For instance version 1.1.0 of Unleashed shows Extra Utilities as version 0.2.4f the server wants 0.2.4e and Natura of version 2.1.3 the server wants 2.1.4 They may have created their own modpack with different versions or chose to update only certain mods instead of following the version number of FTB. If Extra Utilities had not been for a version of Unleashed prior to 1.1.0 and Natura for Unleashed version 1.1.2 and later then I'd be able to identify it more easily. Try to get in contact with the admins or others on the server.
