Qgc daily build issues

I downloaded latest daily build and now lights wont turn on. The camera wont move, wont arm or run. i went back to last build that worked but same issues. Have tried stable build but same issues other than camera tilt was mapped to d pad. Not sure what is going on. After uninstalling, i have done registry clean and defrag then restarted computer.
Wrong timing coz i have demo with coastguard tomorrow.
Help!!!

For the record, we recommend the stable build of QGroundControl now.
