Weird Sleep Mode Trial End Error

[lunaistar]

I just downloaded the trial about 30 minutes ago and tested it out and it worked fine, but when I had to go outside I closed my laptop lid and came back and opened it back up, but when I drew for again for a second a popup came and said my trial was over, even though it's not supposed to be over yet because I just used it once and didn't close the program yet. Can someone please fix this or tell me what I should do to fix it??

Do you mean that Paintstorm could not continue work, or it shows pop up the alert that could be closed?
