MT4 won't connect after win 10 update

My MT 4 wont connect after windows update and I am pulling out my hair.
Tried these , but none of them work
====================================
Rescan server
Restart MT4
Restart windows 10
Delete server.ini
Run MT4 as administrator
Turn off fire wall
File ===> Open account =? login existing trade account
Turn off proxy

I dont want to download and install new mt4 because that wil mean I will lost mean renko bar value on 20 charts on all timeframes which i manually entered.
20 charts x 5 timeframes = 100 mean renko bar value .

Pls help thx. Andy

After a WIN 10 update I always have the problem that I need to put in again my log ins (account number and password). Dunno if that is the reason for your issue. But is annoying as hell and maybe someone knows how to avoid that? (beside ignoring those damned updates...)
