What version of JMRI are you running on your old computer?
What version of JMRI did you install on the new computer?
From the 4.16 release notes:
If you are currently using JMRI 4.11.9 or earlier, we strongly recommend that you update to JMRI 4.12 and make sure that's running OK before updating to this release. Once you have JMRI 4.12 running OK, store your configuration and panel files and use those from then on. There have been a number of changes in serial port support, panel file format and configuration options since those earlier releases, and moving to the stable JMRI 4.12 release is a good way to work through any possible problems.
