your studio likely has no open slots left... you'll need to open a new slot...
on the studio page, click on the 'Facilities' + sign
and then follow the directions to add a slot to your studio
~~you may need to spend diamonds, if all note slots are currently in use...~~
if your studio is currently fully expanded, like ours is, you'll have to 'boot'
an inactive player, or set up a 'waiting list' in your studio notes to wait for
a current player to go inactive...
hope this helps...
