Unfortunately, our virus scanner went into the weekend a bit too early on Friday and this resulted in no more emails being sent. This in turn has led to the system becoming slower and slower and there were problems everywhere due to the load.
We have now been able to fix the problem and all outstanding emails have been sent in the last few hours. So if you have been waiting for an (automatic) email from the system, it should have arrived by now.
We are sorry and we will see to it that we detect such problems in a more timely manner in the near future.
