create a backup error message "This Parameter is incorrect"

I am unable to create a backup error message "This Parameter is incorrect"

Do you get this message when you press "Create" button>> Dialog box with options>> Click OK then get Error message : "This Parameter is incorrect"

I ask support for this issue and they returned with a solution, which I like to share with you.

Some time ago one user informed me about similar problem, and I have found that the problem was in incorrect date of the font file (the date of file was in 1932 year).

This is an issue and I will fix it in the following releases.
(Unfortunately, FontExpert allowed to add this file to Library, but then failed to create Backup with this file.)

To fix it, it is needed to find the font file having strange date (for example, earlier than 1970) and change its date.
(Or copy this font, then remove it from Library, then change the date of font file and add it again to Library.)

All fonts in Library are located in the LIB folder:
C:\Users\<USER_NAME>\AppData\Roaming\Proxima Software\FontExpert\14.0\LIB

I have solved the issue but instead of searching All fonts in Library are located in the LIB folder:
C:\Users\<USER_NAME>\AppData\Roaming\Proxima Software\FontExpert\14.0\LIB

I found it much easier to do it within the application I removed a number of fonts that did not have dates and a few 1980's dated fonts.

I was then able to backup all the font collection.

Thankyou
