Updating S2M Optimizer from a Trial to a Subscription is a pretty simple process. Once you have received your Subscription License via email perform the following steps in S2M Optimizer:
Once S2M Optimizer is open go to Utilities | License Manager.
Click Install License.
Enter the Servercode from the email, select the "Request License file" option, then click Next.
Select the "Remove Existing Licenses" option then click Finish.
At this point you should receive the success message click OK then Close the License Manager. It is recommended at this point to Close and restart S2N Optimizer.
If you have any trouble with this process please let us know in the "S2M Optimizer Get Some Help" forum on eSupport.
