I hope I can get some support as fast as possible, for over 29 hours now I've been getting constantly some bogus API error on my requests, named "CANNOT_MODIFY_FOR_TRIAL_CAMPAIGN", even though I don't have any trial campaigns, and even though I didn't make any change to my API script (that's been running smoothly for a long time) or to my Adwords account.
I've tried emailing adwords api support with the soap log, but still didn't get any answer.
I've had a similar error about a month ago and it got resolved by itself after over 30 hours.
