I installed the official ethminer now and started it with your data - but it can't connect to the server.. don't ask me why. I tried both. The us and the eu one.

ethminer
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100
ethminer.exe -F http://eu1.nanopool.org:8888/0x72_0xD5B1C0b4a418F512D37645F57c0Cba6D44bAdaA0 -G -t 4
