Problems With Soundiver 3 Options

[kaboombahchuck]

I have soundiver running on an iMac 350 indigo using OS 9. Here is the problem, I get the probram to recognise my alesis nanosynth, recieves the data, loads library, the whole nine yards. Everythings works great! Killer program. Untill I quit, and put the computer into the sleep mode. When I go back to soundiver, it says that it is not recieving data from the nano, check midi cables, so on and so forth. No matter what I do, it is a no go.
If I restart the computer, start up soundiver, I can then reload the nano info and every thing is fine, untill I put the computer back to sleep. Any ideas what the problem is? Restarting the computer every time is a pain.
