Most likely i'm going to reinstall the OS.
In this situation, you can do one of the following:
* Re-install the operating system. This is the easiest solution in most cases.
* Edit the .reg files from DOS (Windows 95/98[me=dsantamassino]only). This is extremely complex and should only be attempted by individuals with an expert knowledge level DOS. You may want to obtain the services of a computer consultant if you decide to use this method.[/me]
