unable to open one click trading option

 

Hopefully someone can help me out.

I am not able to open the one click trading option in MT4. Top left corner triangle shows but nothing happens when clicked.

ALT+T does not work.

Settings in Tools/Options/Trade are set correctly.

OS is windows 7 (newly installed)

Broker support was not able to help so far

Any suggestions or ideas what can be done to fix this ?

 
reinstall outside of \program files*
 
Write to Service Desk (you have to subscribe on mql5.com, you have a category for MT4).
