Can anyone help. MFD is missing readouts for altitude,aspd, and hdg. No digital readouts on engine screen either or lower MFD screen. To top it off the HUD doesnt work too. lol Any help?

if you got no displays up an running and if you just installed the ngx it more likely an activation issue, submit a support ticket in.

 

If you just had some number missing just from the mfd etc it will be a font issue do a search on missing fonts and you will get your solution to your particluar problem

 

And in regards to your hud not working since you mentioned it before since more likely due to the activation issue but make sure you havnt pressed the clr button on the hugs panel if you havnt than its a corrupted ddl.xml again submit a support ticket

 

but my guess all your troubles are due to the activation issue
