Youtube generator - exceeded quota
The request cannot be completed because you have exceeded your quota.
This problem could happen, because you only have 10.000 units/day. Different data requests cost different units. For example if you tried to use our Youtube generator's "By search" dynamic slide, a search request costs 100 units, which means you can only search 100 times a day.
So this error message is accurate, that somehow you reached Youtube's limitation.
The best we could suggest is, that you could create a new Youtube API with a different Google user, and use that for today (tomorrow you could put back the previous API's keys, if you want it to).
