Most current audio interfaces are multiclient. The M-Audio 610 is a somewhat older audio interface, the latest driver is designed for Windows 8. It's quite possible that the M-Audio 610 isn't multiclient. I don't remember if it is. Check how many ASIO drivers the M-Audio 610 provides, and if there are multiple, try to addressing different ASIO pairs for each application. It might work.
