Impossible to launch a campaign "en error has occured"
I'm running a non-profit and tried to launch a promotional video campaign throughout the Google display network / Youtube search.
Despite having defined all the fields, the AdWords interface told me that I'm not able to run the campaign due, showing the message "an error has occured" under my settings.
The other formats work pretty well, but I got the same issue with video ad campaigns each time I've tried to run them (it's been 3 months now).
So I'm wondering, does that something relative to the non-profit billing or a simple technical issue?
Many thanks for your help!
