New computer - can't record in old project

Having installed 8.5 and moved my files to the new recorder, I am trying to record a clip in an existing project - just as I have several times already in my old one, but it won't record.

I arm the trac, but nothing will record.  Also, I press the echo button, but I hear no change in the head set.  I can hear myself talk into the mic, but hear no echo (I also inserted echo into the trac, if that matters), and nothing registers on the sound level meter.  When I try to record, I can see a red line in the trac, but when I'm done, there are no wave forms or sound.

My computer is a quad w/8gig mem.

I'm using a Lexicon Omega

Well I am not going to be online much longer so I will say this... 

If it doesn't show up in Sonar but it does work playing Windows Media Player or other programs then:

There is sometime a problem in Sonar in which it will disable a device if it conflicts with another device.... you can fix this by going into the Options(Global or Project.. can't remember) menu and you will have to find it( I am not in front of Sonar to get that specific) but it says devices.... if the Omega is not highlighted(its more like a grey/black highlighting) then click on both input and output... they should both highlight in that dark color.

It will say this will change when you reopen Sonar... so close out and reopen Sonar and the device will be active......

It sounds like it doesn't see your device and is recording using your built in PC sound Card so give that a whirl... I'm out so good luck with it.
