Default [RESOLVED] 425 Unable to build data connection: Operation not permitted

Hello,

I have an issue that forbids me to download a whole list at once.
FlashFXP downloads and retrieves 1 file and when it's complete FlashFXP can't connect anymore to the server, giving "425 Unable to build data connection: Operation not permitted" error, failing the transfer.

Here's an example log:

I've tried every settings combinations I can, issue is still there.
The fact is that I've already downloaded whole lists of files on this server, but I had to reinstall my computer (Win7 Ultimate x64) while I did not backed up FlashFXP settings, forcing me to reinstall it without those working settings.
Or maybe it comes from the last version of FlashFXP, really don't know.

If you have a clue, I'm in.

Thanks,
David.
