I do not run this program, if some accounts work and some do not, then you need to recheck your settings for the accounts which do not work.
This problem your experiencing would be better posted to the actual developers of the program; Microsoft. Oldversion.com just hosts these files, they do not develop them.
The very first place to check for issues would be the developers site. If you can not find a answer on their help sites, then you might want to email them.
