Dear all, I receive a "not found" error, I have uninstalled Trados 2015 Starter and installed it again, but without success.

I have also renamed the .xml files, deleting the .lic file as I found in the comunity but nothing helps, I cannot start it :(

Has somebody had the same problem?? Thanks a lot for your help and regards, Natalia
