If a key does not work, we will replace it free of charge! You have no risk. Since these are usually volume licenses, they have a certain time window in which they must be activated. If you have followed all the instructions and downloaded, unpacked (if necessary) and installed with the link as described, and the key does not activate the software, it may already have expired (you can not see how long the license key has been on the market). In this case, please fill out the form in our ServiceCenter and upload a picture with the error message. You will immediately receive a fresh key for immediate activation.
