CR95HF error code 4

occasionally when I send a  CR95HFDll_SendReceive command, I get error code 4 back. 5 I understand - the USB is not connected, so I simply reconnect, but 4 is a communication error. How can I recover from this in my program? (it does not matter whether a tag is there or now) as currently the only way I can do it is by resetting the computer or running the ST M24LRxx application.
