Hi, been thinking about mining for a long time now, but I am struggling to set up properly, and forgive me if this is in the wrong thread on the forum
![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif)
I have registered on mining.bitcoin.cz, set up my worker etc
When I try and mine, the message at the bottom of the guiminer say's
Username must be in format <login>.<worker_id>
I don't understand, it is exactly how I have it set up in my account page on the slush site, under 'worker'
Can anyone advise more where I should be looking for the mistake?
Thanks in advance
