I did something stupid

When I went to open the Sage it says I have to update the drivers, it tries to install all the drivers but says it cannot updated from the s:\ ..... do I wish to proceed so I keep saying yes, yes, yes, but I cannot install it.
So I tried to find the company file to amend the data directory to point it back to the C:\ and I cannot find the company file.
I am using Windows7 and it is saved the sage into Program Files (x86) and then Sage\Accounts and from there I cannot find the company file.
I have uninstalled and reinstalled 5 or 6 times and it seems to remember it was pointing to my S:\ and I am totally stuck.
Please any help would be great as I am in the middle of my year end and want to cry.
Thanks
Caroline
