Can't start OpenSUSE VM after installing 3.0.8

[BenS]

Hi,

I'd run a OpenSUSE in a VM under WinXP - worked great, but today i installed VirtualBox 3.0.8.
Now I get an error if i try to start the old VM.

'C:\PROGRA~1\Sun\XVMVIR~1\VBoxGuestAdditions.iso' is not accessible. Could not access the image file 'C:\PROGRA~1\Sun\XVMVIR~1\VBoxGuestAdditions.iso' (VERR_PATH_NOT_FOUND
Fehlercode:

Komponente:

What to do now? got important files in this system

Unmount the cd in the guest settings before you start the guest.

Had the same problem with Ubuntu. Unmounting the media from the guest isn't intuitive, because I want to install guest additions!
What you need to do is release/remove the old guest additions, run your VM and then go to Devices->Install Guest Additions.
