Welcome to the Q&A Forum

We had the same issue with one of our client's reports so I did a little digging and came across this post from Jaymerica Industries. They have some good info as to why this may be occurring. http://www.jayratkowski.com/cart-top-google-analytics-landing-page/ 

Hi Schwaab, I'm sorry for the confusion. It looks like we sent you that message without actually migrating any of your campaigns over. We don't have a set schedule for the migrations but it should happen soon. While you're waiting you can either continue to use Pro, or delete a campaign and set up a new one in Analytics. We're sorry for the inconvenience and hope you get to use the full awesomeness that is Moz Analytics very soon. If you have any further questions email us at help@moz.com. Cheers, Sierra

Hi there! I haven't had this issue with the new Keyword Planner, but have received this message in the past when doing fast and furious keyword research with the old tool. More often, though, I will receive this message when performing search after search like a madwoman (in universal search, logged out.)
