Normally, this message indicates one of the following conditions:

• You've used LicenseControl's "Find this Application's License and Activate It" operation when the application/plug-in is not yet licensed for this system. This operation can only find and re-activate the license on a currently licensed system — e.g., in a case where the system was restored from a backup or copied to a replacement disk. If the license is not already activated on that system, you'll need to supply the License ID to perform the initial activation.
• The license was recently purchased but has not yet been "posted" to the licensing server by the e-store from which it was purchased. Some e-stores can sometimes delay a purchase (e.g., for approval, etc.) so you should wait a while and try again. Many e-stores send the purchaser an email to indicate the purchase has been completed. Once the e-store's computer contacts the licensing server, the posting will be completed and the license(s) will immediately be available.
