682 donor - after loss of connection no new synch possible

[XE-Fanclub]

Hi everybody,
I am using this wonderful prog to synch between 2 computers via LAN. Unfortunately, the target computer started a reset while I was copying many files. And now the host cannot reconnect with it. FC always freezes. Is there a file I must delete before I can try again?

Forgot to mention that I use the portable version: x 64 on host
