In some situations it may be necessary to reactivate Enterprise Studio, for example when your software license needs to be updated because of the purchase of new functionality, if the usage period has expired, or if Enterprise Studio has stopped working. Check which release of Enterprise Studio you are running, and follow the appropriate procedure for updating your software license.  If you are not sure which version you are running, you can check it via  File > About  in Enterprise Studio.
