Fontbrowsers not showing renamed ttf's

[lex-illustrator]

Hello

Does anyone have any suggestion, why a couple of fonts stop being able to be shown in a fontbrowser (both Fontlister and The Font Thing), when you rename the ttf-file with the program - TrueType Renamer?
I do this action, because when you download a couple of Freeware ttf-files they sometimes have different file names than the names of the fonts. So the program only changes the filename excactly in the fontname.
Is there any easy action, which could change the not showing in the browsers.

Greetings, Lex van de Oudeweetering

I now experience that after a restart of my computer these fonts show in the browser. I'm glad and at the same time stupified. These fonts are not in the Installed folder.

Thanks

The registry data may be corrupted; Windows might have fixed it during the reboot.

When this happens again, run FiFoFo.
