PC - can't log in to any account on any server (launcher works, game fails to start)

[Finn42]

My other computer can log into all the accounts, on any server just fine. So Its a Local problem.

So launcher asks me for my UN+PW I enter it in, it then prompts me to choose a server.
I can choose ANY server:
I get the message
"getting in line to connect"
Launcher exits
and instead of the game launching.... nothing happens.
No DDO process in task manager - nothing.

--
Just before this I had a DDO crash and it lost my saved info (aka, which account name to pre-populate the launcher with) -- I tried to do a DDO repair.
I just finished doing a complete uninstall and re-install. still the same problem as above.

any advice?
thanks.

Windows 10 PC - I didn't change any hardware or software (to the best of my knowledge, who knows what windows updates in the background these days...)
processor: AMD Phenom(tm) II X6 1090T Processor 3.60 GHz 64bit
Ram 8.00 GB
Graphics card NVIDIA GeForce GTX 560


I also did another fresh uninstall, manually deleted the documents->DDO folder (where layouts and such files files are that do NOT get removed with uninstall) -- still same thing.
