Ad not showing for strange reasons.

Ad diagnostic tool is giving me wierd reason for different keywords I check

[deep_alley]

I search for a few of my keywords on google, and my ads aren't showing up. When I run the ad diagnostic tool I keep getting varied replies for different keywords. In one instance the diagnostic tool said that I have exhausted my monthly spend, which is ridiculous cause my daily budget is higher than my over all spend till now (account running for a week already). My bids are pretty high too.
Anyone had this problem or know whats going on? I have writen to google but will only know whats going on tomorrow.
Any suggestions as to what I can do? Already increased my daily budget.

Have had a serious problem with this all this week.

Budget was $100,000 per day to ensure max visibility, good history with 20% CTR on average and the ads not showing.

One account was on credit terms so started a new budget and that fixed the problem. Other account was credit card so took the KWs & placed in new adgroup. Lost the history but KWs are back again.

Ad diagnostic tool showed "unknown" as to why ads not showing ..... very helpful...

Both queries sent to engineering for examination

I've found that the diagnostic tool quite often just throws out random nonsensical reasons for an ad not showing. For example, I've had it say "adult content" when there is no adult content. Then I run it again and it doesn't give me that message.

No reply from google yet.
Well even I see silly reasons at time. I have noticed thought that when the ads are still to be approved the reason thrown out by the ad diagnostic tool is mostly 'adult content'.
Well I think I'll start a new campaign with the same words and see if it makes a difference. Cant keep waiting.
Thank.
