Error opening projects created from Marketplace samples

I just upgraded to 4.4.0 and I downloaded some new samples from Marketplace I haven’t looked at before. When I create a new project and try to open it afterward, I get below error:

SIGSEGV: invalid attempt to access memory at address 0x3

EngineCrashHandler(FGenericCrashContext const&) Address = 0x66d268f (filename not found) [in UE4Editor]

_sigtramp() Address = 0x869ba5aa (filename not found) [in libsystem_platform.dylib]

My other projects open up fine. I tried this with different examples from Marketplace, but they all have same error. I’m running UE4 on OSX 10.9.4 with a 3.4 GHz Intel Core i7 and 16 GB RAM. Graphics card is NVIDIA GeForce GTX 680MX 2048 MB. Stack trace is below:

Hey Harrower,

Can you and attach crash log from a project in which this occurs? Thanks!

Here you go. I can’t even get 4.4 to launch now.link text

Thanks! It looks like engine cannot compile some shaders. Please try Verify option for 4.4 in Launcher and let me know if that fixes it.

That actually didn’t work, but I deleted and reinstalled and it looks like everything is working fine now. Thanks!
