$ERR_XFBADPKTID
550
Incorrect packet identifier
The parser cannot parse the return response due to an invalid character in the packet type field. Because this xfNetLink Synergy error is sometimes caused by network noise, try the operation again. If you get the same error a second time, contact Synergy/DE Developer Support for assistance. If you are connecting a newer server to an older client, you may need to upgrade the client.
