Solved : connect Mql5 in metatraderX : authorization failed

 
When I try to log in to MQL5 in MetaTrader 5 or 4, I get this error: "MQL5.community authentication failed."
However, I am sure my login password is correct because I successfully logged into the MQL5 website using my browser.
It was working fine last Friday, but today this error occurred.

try to change your password and then try logging in again. Only few days ago a user had same issue and reported that that worked for them.

 
Thx a lot, it works,
I changed my password and I also delete my  Community folder as I found it in a topic , and I do not know if one or both actions are important but now it works
Actions : 
-change password
- removed all files in folder : C:\Users\user\AppData\Roaming\MetaQuotes\Terminal\Community
