THEMA: Error in subscription of youtube videos

Good evening, for some days the credits that must be added by subscription in YouTube videos do not add up, can you help me.
We are not able to update your balance. Error code sil-5 - please try again in 30 minutes or write to mail to our support.

We checked everything and we can't find an error.

For explanation:
There are 2 different ways of earning with youtube:
- Youtube Views (0.8) credits
- Youtube Subscription (12 credits)

You can see on the compaign if it is a "view" or a "subscriber" campaign.
You can get only view credits for a view campaign and subscriber credits for a subscriber campaign.
You will get no subscriber credits for a view campaign!

To get view credits for a view campaign:
Click on the Youtube "view" campaign - a new window will open - watch the video for 30sec - on the old window there is a counter of 30s - if the counter is finished you will see a "get credits" button - which needs to be presses to get credits.

To get subscriber credits for an subscriber campaign:
Click on the Youtube "subscriber" campaign - subscribe the channel - click on "update credits" button in the top of your user panel to get the credits.

Credits can always be checked here:
