Failed to load dataset 'MainTheme.xml'

When I replace videoplayback example with new xml and target and want to run with ios 5.0 it is showing error failed to load dataset .

But other wise when I run it main file it's Ok .

My xcode verion is  4.5.2

And OS is  Moumtain Lion (10.8.2)  and vuforia-sdk-ios -  version is - 2-0-30

Is there any problem in xcode and lion  or vuforis version ?

Can you check that the .dat and .xml are both in the project?

Sometimes in XCode when you drag the files over they do not get copied into Bundle Resources, so you need to check the Copy BundleResources section within the Build Settings.

Also, what exactly does the xcode log say?

Thanks for your reply , it's OK now .

This problem is present only one jailbreak device , but in other devices , it is running properly .

This issue is fixed now .
