suse 10.3 installation issues

[pricesully]

successfully installed
but each time started VBox it told me to update the software
so that is what I have done and when I start the program nothing appears to happen
so I have uninstalled and re-installed and it says the directory does not exist

I assume the uninstall was a failure
can someone tell me where all the installed items will have gone and how to get rid of them manually
and then I will re-install again

thank you in advance for any help anyone has for me

I'm new to linux, so am willing to believe it's my fault and not that of the software
