Problems with registering Mathcad 15.0 Student Edition (please advise)
I just received my Mathcad 15 student edition purchased from JourneyEd.com. After entering the product code supplied in the factory sealed shrink wrapped box, I encountered the following dialog box after the first and subsequent attempts to register the software: " Thank you for using Mathcad, Single User edition. You have reached the maximum number of license files available for your license type. To aquire another single user license, please visit http://www.ptc.com,..." As I said I just received this software, never attempted to load it on any other computer or the computer in question. Prior to purchasing this software I had Mathcad 2001 student version loaded on this computer, the program was uninstalled several weeks ago. I was able to register a trial version on this computer as an interim measure. What can I do fix this problem? Thanks in advance for the help.
