Unable to purchase and update Ea. How should this problem be solved ?


Is this problem caused by windows update or not which was working normally before.

-I've gone back and looked at the forums and made sure to follow most of the solutions. But the symptoms still didn't go away.

MQL4 Market: failed to load products (get header failed [12150]) blank pages in markets

The bug has been fixed. Restart your terminal and check the Market.

If your Market is still empty, do the following:

  1. Close your MetaTrader 4 terminal
  2. Go to C:\Users\{user name}\AppData\Roaming\MetaQuotes\Terminal\Community
  3. Delete mql4.market.en.dat
  4. Open MetaTrader 4 terminal
  5. Go to Market tab and wait 5-10 seconds until the new database is downloaded
