ValueError: need more than 1 value to unpack

[tom-burman]

Hi, im new to the mining scene, and have tried setting up GUIMiner, but when i click start mining i get this error:

ValueError: need more than 1 value to unpack

Any ideas? I have an account and worker with slush's pool and as far as i know ive set everything up properly.

Thanks

EDIT

Ok i re-opened GUIMiner, and re-entered my details but now i am receiving these error messages in this order:

No JSON object could be decoded
