hey all. I just loaded up FM5 to continue work on my Lotus E21. Everything appeared normal, but as I went to save a new logo, I discovered that all my 100’s logos and designs are all corrupted with a No Valid Data message. Also when I select a car from the garage I have no car images on the screen, but I can select them…please don’t tell me I’ve lost all my work. The career has however been saved.
Can you select a car, and open it to paint, and select and save logo’s from the car? Just a desperate thought…
Or even save the existing car paint with a new file name?
No option I can see will retain your shared version for credits, unless they are still out there collecting now.
Definately send a PM towards Helios and an email off to T-10, but that’s desperate in itself.
I can download my old car designs and save it. I can access that in my design catalogue, but all other spaces are filled with invalid data. My logos are not saved on storefront and cannot access them at all 
Your cars in garage don’t already have a paint on them? Oh, you did open wheelers and used same car for almost everything.
I just figured you could select a car from your garage and then open the car for painting, hopefully it has a paint on it still,and then just rename and save, or select all the logos grouped in it and save them separately. But you had a gazillion paints just for the E21, and a couple other open wheelers…
I don’t have a tenth of what you had and I’d be crushed. I hope you can recover this.
Yeh, none of my cars have paints on them…they are invisible until I paint them…Yes I’m crushed. I couldn’t/wouldn’t start over. I couldn’t face spending another 2000+ hrs again to find they wont import to FM6
Try this. Unplug ur modem then in the dashboard go to Settings > System > Clear Local Game Saves. Plug back in, Start the game back up and when it goes to sync cancel it. Then exit and start the game again. It should give u the option of loading the most recent save or an older one. Load the older one from the cloud. I have no idea if this will actually work but it was my plan if I were to have a gamesave issue.
Not sure that vinyls and designs are saved to the cloud. Not wanting to do anything until T10 respond again
To the OP, can you please try exiting the game completely, then hard reboot your console and fire up Forza 5 again. Let us know if the problem persists.
Unfortunately it’s still the same. The cars ( whether painted or not) in my garage selection screen are invisible. They appear once again when I repaint or erase paints. I also have “invalid data” when I access my gallery too. If I could download my designs without them being locked off the storefront, I guess I could resolve the issue… Thanks for looking into this 
Same problem

Oh yes, Xbox asked me to confirm my gamertag email and password which it never normally does. All okay in FH2.
This also happened to me. I also lost all my pictures, videos and tunes. All had blank boxes, but I kept All my money and my level. Ended up emptying my blank garage because they never came back. I’m pretty sure it happened when I was playing Forza while downloading another game. Maybe data got crossed up.
