yes, i tried removing it and adding it again.
i did these things:
1) removing it and adding it (ethernet controller)
2) i booted into the recovery mode, checked with
dmesg | grep 'eth' to see if there was a networkcard installed and it was
there i also saw an eth1 (tho there is only 1 card configured in the vm settings)
then i tried to bring the card up:
ifconfig eth0 up but then it told me that there is no such device
i checked for conflicts (i believe with: cat /proc/net/dev (cant remember cuz it was last night and i am at work now)) but everything was filled with 0 which according to the page i used is a good thing
3) tried using vmware converter to import and convert the 5.x image to a 6.x image, same problem but now also the iso file couldnt be found
4) tried using the vmware server image but no luck there either
