Hello, I have two laptops, one old and one new. Both have Adobe Acrobat X Pro installed on it. On the old laptop I have de-registered the serial key and uninstalled Adobe Acrobat X Pro. On the new laptop I have entered the serial key and it says invalid. I have checked both versions and they are the same version. I also tried to contact Adobe Support and they were no help and told me to post a discussion in this forum. Please get back to me as soon as possible. Thank you.
