Greetings, could you please clarify if you tried to run the launcher as admin? Also, have you checked if the launcher is blocked by antivirus/firewall software?
in case both workarounds did not help you, please make a screenshot of the issue, then open Windows Command Prompt (press Windows + R), then type:
%HOMEPATH%\AppData\Local\Ultimate Admiral Dreadnoughts\log
There will be log files from the launcher (e.g. 25.02.20.txt)
Please copy the latest log file and screenshot, then contact Xsolla support team via live chat option (help.xsolla.com) or email (support@xsolla.com), describe your issue and attach both files
You can also try to uninstall the game and install it again.
