I've had a search through the forum and I thought I struck gold straight away! Sadly, no.
All my P3Dv5 aircraft have installed impeccably...Except the Cub. It's there ready for selection but the paintwork is all fuzzy. I've uninstalled it, it turned out I installed the P3Dv4 by mistake.

Got the v5 version and installed that. Still fuzzy. Ah! I found the post about starting P3D after the uninstall THEN reinstalling. This HAD to be the answer....Oooh no it wasn't!
Where now?
P.S. I did ensure I had the right specs on.

The World is divided into two groups. Those who say "Give me a link" and those that provide the link.
