Cannot Retrieve MathCad 14 license over the Internet - Server Error I had a PC failure and now need to reinstall MATHCAD 14 (yes, old version, I know). I installed the software with no problem, but when I go to retrieve the license code over the internet, I continually receive a server error, with some gibberish language in a dialog box about a header being wrong or something. I just need to get the software license so I can get back to work. I have all of the product codes and CDs, and have been a MathCad user since version 8. Please help - this is quite frustrating. Thank you.
