Hello,
while trying to install a font from the Font->Install menu item I get an error telling me that "The “Fontinstaller.dll” program is compiled with EurekaLog 6.0.18 triam version. …
When clicking the OK button Fontcreator is closed and unsaved data are lost.
The About box is OK and displaying the right registration information. 
Thanks for your help.

Please uninstall your current version of FontCreator and download the latest version as available on our website. Or wait two days and you’ll be able to download our upcoming release FontCreator 6.1…
Thanks,
issue is fixed, but I’m a bit confused about the program version… both (the previous one and the new one) display the same revision 6.0.1

You might still have had a single file from version 6.0.0.
