'Invalid host' error when starting Maple

"Invalid host" is a variation of the "Invalid or missing license file" errors. It indicates that FLEXlm (the licensing software used by Maple) is reading a different Host ID (or Disk Serial Number) than the one in the license file (created during activation of Maple). This could happen, for instance, if you upgrade your operating system, or the order or addresses of your network interfaces has changed. 

If you have an additional activation remaining, you can simply reactivate Maple. Please note, however, that this will decrement the number of activations available for your Purchase Code.

Alternatively, you can contact Maplesoft Technical Support, support@maplesoft.com. You may be asked to provide your complete Host ID information, including your read host ID, while your network connections are off.
