Hi Mauricio,
You might be able to find errors in SLWatchdog2.txt in the Logging folder found in Skyline DataMiner to see why the license is being rejected.
I would create a support ticket to reach out to Techsupport to further investigate or reissue the license file.

The SLDataminer.txt log file should also give more details if you are having license issues. More details on how to troubleshoot it here :
