pool stopped recognizing my worker? (noob questions inside)

Hello

I got hands on an Antminer U1 and started playing around with it. After getting the right drivers I started mining to give-me-coins.com and all worked fine for 2-3 days (I could see my hashrate on the pools website)

Now I checked and the pools website doesn't show any connected worker, where bfgminer is still working fine and reporting accepted shares screenshot.

I didn't change anything, neither on the website nor in the batch file I start bfgminer with. What to do? Where to start with troubleshooting?
