Hello,
There is a line that is probably missing in your license.dat.
You have several ways now.
You can look at the file you received and make sure you paste its content into the existing license.dat correctly.
If it's ok, it means you better submit your license for it to be corrected.
Create a new service request (see my signature below) and make sure to include your license.dat file.
Also if you have any license purchase reference, put it as well as it will speed up the resolution.
Finally, you need to include in your posts on this forum, the version and core of CodeWarrior you are using. Otherwise it is not possible to help you nad YOU will have to wait longer for someone to ask for it again...
Alban.
