Failed to initialize the QCAR SDK

September 3, 2011 - 7:51am #1

Hi,

I had a running project where I just did some graphical changes and suddenly I can't get the app to run again:

I've restarted the Mac, iPad and created a new project and install qcar again. but I can't compile any QCAR project; even an empty scene (just a arcamera and an imagetarget) won't run.

Any hints?

3G should work, perhaps it was just a one-off connection problem? Let us know if you see the issue again.

I've switched from 3G to WLAN and it worked. Is 3G not working or could it be that there was just a connection problem?
The tracker is named "final" and is there and working.

Confirm that you have a working connection to the internet.

Also do you have a trackable named 'final'? If not, check that your trackable resources are accessible to the project.
