I was able to solve errors 58 and 54, but now I get error 59 when trying to connect to a bluetooth device. This is a little frustrating... I´ve been using simple server and simple clients examples form LabView 8.
If you are receiving error 59, make sure that you are executing the server before the client. The connection has to be open before the client can find it. Also check to make sure that the server address is correct in the client. I'm assuming that you are receiving error 59 from the client, but if not, if you could let me know exactly which VI is generating the error.
Also, make sure that your device is on this list of supported devices in XP SP2:
