Not off to a good start

Downloaded the free version and couldn’t get the markers to work. Figured it must be something to do with the free version. Bought the $25 version. It took my money okay but didn’t give me a link to download a full version or instructions for anything. Got an email to confirm they got my money but no link to instructions or a download. Sent an email and 3 hours later no reply. Not looking good at this point…put my 25 cents in and got no candy bar.
