CD burn cannot detected from my computer!
Hey guys, I want to install Adobe Photoshop CS3 on my desktop computer but I don't have an original installer that's why I went to my friend who is working at computer shop, my house is just 20mins away from the computer shop. I requested him to burn a 2 copies of his Adobe Photoshop CS3 into a cd. After he copied it at the cd, he tried to run the software and it is working normally. Then when I went home I'm excited to install the Adobe Photoshop CS3, but unluckily  the cd cannot be detected at my dvd rom. Before I left at the computer shop the cd is working but now why is it cannot detected from my pc. Is it a cd error or can be a cd/dvd rom problem? What do I need to do to make it work?
