How to restore tables?

[Sunburned Surveyor]

I had a problem with my MySQL server, and I had to reinstall it. I wasn't able to do a dump of the data before the server crashed, but I did copy the "data" folder and the folder containing the Inno DB files from my hardrive. I have now reinstalled MySQL, but when I try to replace the folders, I am no longer able to log into the server, even as the root user. I did not reinstall the former "mysql" folder with the old user tables, and I also used the same passwords as I did on the former MySQL install so I don't think that is the problem.

How do I restore the databases from the old server? Is there a way to do this?

I am running MySQL Server 4.1 on a Windows 2000 Machine. I only had 2 databases on my old server, and they were fairly small in size.

Thanks,
