I am new to Quant Connect and have been busy trying things out - mostly trying to debug my algorithm.

Now, when I try to run a backtest, I get the follwing error message:

     API Error Message: Sorry, you have reached the maximum number of community backtests per day.

I didn't realise there was a limit (help pages say there is no limit to the number of backtests). I have a paid seat, if that makes any difference. 

What is the daily limit on backtests please? And any tips for running debugging backtests without hitting the limit?
