I received my CA ERwin DM r8.2 license and applied that, however, I am not able to apply any more than 25 objects in the model. ERwin is still coming up as a demo application.
1) Make sure you install the license file using the Help | Licensing | Install License File button.
2) Double check the license is located at the same directory as the default community license
3) if 1) and 2) are verified, Please go back to Help | Licensing, review the MAC address on the screen, and compare the HOSTID field in the license file CA sent you - make sure they match 100%
4) if 1)2)3) are all correct, try renaming the default community license to *.old and then re-launch CA ERwin DM - sometimes there is a refresh issue in reading the license.
