Your dual login was disabled for technical reasons. Please use only 1 tuner to watch 1 channel at a time, not more.
Sky DE and SkyUK packages send 1 request per 8 seconds instead of 1request/10 seconds. That is why, the number of requests sent by your tuner is considered increased.
We have refund you, sorry.
For future: for technical reasons, dual login will not work for SkyUK and SkyDe anymore.
