can't import my 0.90 .crafts?

[Somtaaw]

Along with having issues with my career modes tech tree (somewhat covered in another post I did), I'm now finding out 100% of my, personal, crafts no longer work from 0.90 or earlier versions.

Go out and download some other people's pre-1.0 crafts? Works fine, even when I strip the craft apart and find numerous clipped stuff everywhere.

Go back and check my clipped craft? Still unloadable.

The only mod I had/have on any craft were MechJeb control panels, and I have MJ in both 0.90 and 1.0. I am so confused why my 1.0 apparently blows and is saying "nope, you can't play anything from old. Go back to fresh career m8"

Can you specify? Does it have missing parts, or does it not work as it "not doing it's purpose?"

Every single craft says "incompatible" parts and won't load in the SPH/VAB. However, every single one of those craft are also currently sitting in space, and weren't deleted upon career load after updating to 1.0

But I just loaded my 0.90 backup KSP, and every single one of the craft is only using, at best, a MechJeb control panel for modded parts. Some of them rely heavily on clipped parts whether for cosmetics, or other, but exluding MechJeb there's nothing there that would cause "incompatible parts". This could be an extension of my tech tree being incomplete (i'll snag a picture of that and upload it), and I'll check a sandbox 1.0 to see if my 0.90 career crafts load in the sandbox.

Edit: and yes, I do have the 1.0 edition of MechJeb in my 1.0 KSP, so there shouldn't be a compatibility issue there.

Ok, yes it appears this issue is also directly coupled with my tech tree failure... a 1.0 sandbox has no issues loading my 0.90 craft, but my 0.90 career loaded in 1.0 KSP has whole sections of my tech tree being "gone" and no amount of tweaking with the debug tool fixes it.

So I have the option of messing around with sandbox and kissing my old career goodbye, waiting for a fix and still messing around with sandbox before going back to career, or starting a brand new career.
