Can't load sample dataset

Hello! I can’t load sample dataset, it tell me : “An error occured loading sample data: Target cluster does not have enough free space to import dataset”.
After many attempts to solve this I have not succeeded. What should I do? Thanks a lot.

You might have already loaded sample data or having another free cluster
Drop all old clusters create new and load the data

There is 500MB restriction and your smaple data is around 350MB
It is not being accomodated means you already used the space for another cluster/project
Please go through our forum threads
You will get more details

Ok! Thanks a lot!
