The system cannot see that the Ea I bought has been updated,

[Mehmet Ozhan Hastaoglu]

Looking at the market in Mt5, it looks old version.

Looking at the mql5 site, the new version.

Also the purchases section for the mt5 should be on the splash screen.

I think the system is reading the pages from the cache.

• You can try to install updates on your Windows 10 64-bit computer, and
• check the build of MT5 to be sure that your MT5 is on the last stable build (3802).
• Check MT5 journal for any error related to the Market (error number).

Besides, check the procedure about how to buy EA from the Market for some steps, for example - Community tab and so on:
