You need to contact PTC Customer Support for assistance with your Mathcad license activation. The messages you received—"server busy" followed by "used up all of my uses"—suggest a problem on the licensing server's side, possibly due to the initial unsuccessful activation attempt consuming one of your allowed uses.
Next Steps
-
Do Not Try to Activate Again: Further attempts may lock your license completely.
-
Contact PTC Technical Support: This is the only way to resolve the "used up all of my uses" error, as they can reset your license count on their server.

If you're in another region or need a local number, check the Mathcad Contacts page on the PTC Support website.
-
If you purchased Mathcad with a maintenance contract, ensure you have your Service Contract Number (SCN) or other account details ready, as this will expedite the support process.
Explain to the support representative:
-
The exact product and version you're trying to activate (e.g., Mathcad Prime 10).
-
Your Product Code or License Key.
-
The sequence of errors: the initial server/connection error, followed by the message that you've used up all your uses.
They will be able to verify your license and likely perform a manual reset or activation to fix the issue.
