HOW I SOLVED
I will try to explain what i did to solve the problem.
Maybe i can help a few people with that.
I unistalled the LotATC, after that, and this is very importand, i deleted all the REGEDIT records, in REGEDIT i looked for all references about LotATC and deleted them all.
In addition, i searched for the LotATC folders on the SSD and HD, any folders with LotATC references, and i deleted them.
In summary, i did thorough cleanig of LotATC on my computer.
After all this actions, i reinstalled the LotATC SERVER version 2.2 for my two DCS installations, RELEASE VERSION on the SSD and OPEN BETA on the HD, and everything works fine, and better and fast.
Just for clarification, i use LotATC Client 2.2 on my Notebook and now it works well with open servers on my PC (Release or Beta).
