virtualbox.org

Hi,

I am using virtualbox to run ubuntu on my mac for work. I have upgraded my mac to Yosemite yesterday and ubuntu doesn't start anymore, showing a critical error.
I have tried the repair disk permissions procedure but it did not fix the VB problem.
I have attached some screenshot highlighting the issue.
I have no idea what to do. If i uninstall and reinstall VB I guess I will lose all my data on ubuntu?

Thanks for your help

Install VB 4.3.24. Use the VBox_UnInstall.tool to uninstall the current installation. You won't lose anything.
