i cant import a preflight-profiles to other PCs or Mac.

I made my own preflight-profiles, 

an i can export them.

1. on PC and mac i cannot import the .kfp-Files on other PCs or Mac.
2. on my own maschine i can import and export - there is no problem.

3. i also tried to exchance the .kfg-Files in the Preference-Folder.
4. i tried the "Sandbox-Solution" on Mac, but it didnt work.
(Preferences -> Securitiy (advanced) ...

is there a simple solution?

Otherwise i had to make new -Preflight-Profiles on every single computer.

Thank You very much for help.
