I recently purchased a Student edition of Adobe Acrobat X Pro. I verified my student enrollment and already have the serial number for the program. After which, I followed the instructions and inserted the DVD into my drive. At that time I was prompted by my computer that there is no disc in the drive, when in fact there is. I have already re-started my computer multiple times, and tested the drive other DVDs/CDs (it works fine). This leads me to believe that the installation dvd is, for some reason, not working well. I already registered my product online and was hoping to get some direction as I am anxious to use this product. Please help!
