Client crashing upon attempting to join server

[HeadsDesignZ]

One of the players on my server has recently begun having issues. She was able to play a day or so ago, quit voluntarily, and now can't log in anymore. When she attempts to join the server, it shows the dirt "Logging In" screen, and then crashes back to the technic launcher. I am still able to connect to the server just fine so I don't think it's a server side issue. She has also deleted and reinstalled the modpack... twice.

 

Thanks for any advice/help in advance.

 

I have copied the log of when she attempts to connect:
