In essence it's a meaningless message. PokerStars provides up to 30 observed hands (hands from tables you're not seated at) per session. This is so HUD users can use the information to select a good table/seat to play at. Once the 30 has been used up you'd have to wait for a period of time before PokerStars will show anymore.

This is separate and different from importing your own PokerStars hands while playing, which has no limitation. So I suspect if you're asking this question perhaps your PokerTracker4/PokerStars configuration isn't quite correct - you'd want to have a look at this guide: https://www.pokertracker.com/guides/PT4/site-configuration/pokerstars-configuration-guide

To double-check your PokerTracker4/Pokerstars configuration you need to:

1) Be sure when installing Pokerstars that you choose "English" if offered the option;

2) That in Pokerstars you've set "Save my hand histories" under "Options -> Instant hand histories..." and note which directory Pokerstars intends to put them in (for Vista/Windows 7 users it is often a folder such as "C:/Users/some_name/AppData/Local/PokerStars/HandHistory"), then

3) Once you enable that option play a couple hands at a table (without PokerTracker4) so that Pokerstars will create that folder;

4) Using the guide I linked above be sure that the directory PokerTracker4 will look for new Pokerstars hands in is the same one you noted in step #2. Also while on that tab make sure the "Get Hands From Site While Playing" has a check mark.

Then after taking a seat, click "Play Poker -> Get Hands While Playing" and you should see your hands being imported (and the HUD appear shortly after).
