Board server 10.1.4 upgrade

Hi community, after uninstalling board serrver 10.1.0 and reinstalling the latest one 10.1.4, the databses are conserved in c:\Board......, but after launching the same old conncetion in my latest board server localhost, the board server do not give me access, i tried to login other board server outside my localhost, and it's working as usual, i think the problem is related with the licence that i used on the old version(10.1.0) is there something i can do to solve this problem noting that my licence did not expired, thanks for reading and helping if it's possible.
