Hi 

Try Updating your Windows: Start Menu>Settings>Windows Updates  then try Start Menu> Restart Computer. Try again and that should work go up to E-File at top >Electronic Filling>Convert/Transmit hopefully This helped.

This can be also cause by your antivirus not running in real-time and you will need to see an IT professional about that matter.
