It's weird. Summer is about to begin and I'm finally having a chance to have some fun with my tablet and photoshop...Except that it want's me to give the serial number again. I already did it in autumn but haven't had the chance to use it for the past two months due to my chaotic schedule. Does it really have something to do with it? I went to licensing.adobe.com and it said that "Adobe does not recognize you as an authorized user of this web site". As a student my funds barely got me this product and the mere thought of money getting wasted terrifies me. It would be wonderful if someone would like to help.
