530 Login incorrect

I just installed version 1.5.991 on a Windows 98 box and I can connect to the ftp site, but it comes up with the 530 login incorrect error and disconnects.

I know it is the right user name and password as it works on my Win2K box. I have checked, rechecked and double checked and I know the u/n and p/w are correct.

Any other ideas?

Also, a couple times when I launch SmartFTP I get an error: "missing reference to a history item or favorite item to restore the remote view", when I click ok it will continue to load.

Any ideas?
