I have the same problem as above...at first my STO launcher wouldn't let me engage. and after an eternity when it does and i log on to my toon, it disconnects me, so i tried to reinstall and now i can't even log on due to the same as error as the one you have.
Currently trying to download the file from the first post.
Turns out i have the same file as the one posted on the first post..that means i am back to the original problem of launcher taking an insane amount of time to highlight the engage button."
I am not facing any connection problems (5mbps connection) nor do i have an Anti-virus or firewall running. HELP!!
