software install on Win 98

I've downloaded bas805.exe and saved it to C drive. When I try to install the the software it asks for a password which I assume is the password I registered with.
I typed this in but the OK button on the password panel will not respond. Any ideas?

The password you use will have been emailed to you when you downloaed the software, it is not the same as the password you use to register yourself or use to login to the forum etc. If you are using the emailed password, check your shift-lock light etc.
