Just trying to reinstall Framemaker 10 on a new computer, can someone help?

I had Framemaker 10 installed on my previous computer and apart from requiring a FM10 Licensing Updater solution, had no problems with it. For several weeks, my computer was acting up so I got myself a new computer. I deactivated Framemaker 10 on the old computer and then proceeded to install it on my new computer. I kept Framemaker 9 on my old computer and brought it over to my new computer without any problems. Now it is not accepting the serial number of the Framemaker 9 application when it did before. Has anyone experienced this problem and found solutions?
