I successfully installed MathCAD's free trial, but when asked to license, I attempt to connect to the internet to acquire my license code and am met with the following "Unexpected Error": Thank you for using Mathcad, single user edition. You have reached the maximum number of license files available for your license type. To acquire another single user license, please visit
http://www.ptc.com, a local retailer, or a reseller. To acquire a volume license [[which I don't want, nor need to do]], find your regional PTC representative at
http://www.ptc.com/purchase/contact.htm. PLEASE HELP. I need to run this and am extremely frustrated that I can't. I have never used Mathcad before, much less had it installed on my brand new laptop, so the license error is confusing.
