Depending on the characteristics of the license you are using, various actions may have restrictions. An example is the number of possible signatures per day. Once the limit is reached, the application continues to work very slowly.
If the license used is not sufficient for you, please contact us at the e-mail address about a license upgrade support@intarsys.de in connection.
It is best if you let us know the license key you are currently using. You can find this under the menu item EXTRAS > LICENSE MANAGEMENT at the far right.
