Just upgraded to Pro Need Help

I was unable to add any new ads to wp quads it kept telling me. error can not save settings, try again. I have been battling with it for the whole day. The few odd ads I have there are running, but I can not add any more nor can I adjust the ones that are present.

So I decided to bite the bullet as I have just written a 3550-word post and wish to put ads in it. Needless to say after uploading the pro and activating it I am still having the same issue. So 49 euros out of pocket and no better off. I am not happy, to say the least

If you can help me sort this I would be very grateful
Thanks
Tony
