For anyone suffering from a similar problem, Metaquotes Service Desk recommended this:
Please, update your terminal to the latest pre-release build.There are few steps to update:1. You should open demo account on MetaQuotes-Demo server and log in.Accounts -> Open an Account -> click "add new broker ..." -> enter demo.metaquotes.net -> click "Scan" -> select demo.metaquotes.net -> click "Next".2. Restart the terminal.3. Wait until "LiveUpdate finished" record would appear in Journal tab.4. Restart the terminal once again.
5. Check terminal's build.
It worked for me. My terminal would not auto-update beyond version 985 with my broker. The latest version from metaquotes fixed the problem.
