Assuming you have an install disc, you should be able to get the missing font files off that (attached link gives details of one way to do this using msconfig, but it can also be done from the command prompt).

I suspect that as an alternative to doing a complete reinstall, you might also be able to use some tool or other to fake up suitably named fonts just to get things working again.
