I have just upgraded to Ubuntu 11.04 and it works great. The only problem i have is that i cant access my MS-Windows environment. I am running my virtual box in Ubuntu 11.04. Is there a way to rectify this problem without having to re-install the virtual box coz by this i will loose my docs in the MS windows environment?
When i run the virtual box the following error appears:

RTR3Init failed with rc=-1912 (rc=-1912)

The VirtualBox kernel modules do not match this version of VirtualBox. The installation of VirtualBox was apparently not successful. Executing

‘/etc/init.d/vboxdrv setup’

may correct this. Make sure that you do not mix the OSE version and the PUEL version of VirtualBox.

Thanks.
