Error when connecting

I play on the server with the account epic13 and recently I have been getting the error : internal exception: java.io.IOException: Bad packet id 83
when I try to connect.
Is the server down or is the a problem with my computer?

I think its your computer because weve been playing all day yesterday

This is Jahorscovich, and I also haven't been able to play for a while using either the web version of minecraft or the .exe file.

i think it is because i forgot to add you to the whitelist, lol

ill add you now
