Multiple Delta 1010 Cards - 16 bit only?

First of all, greetings Cakwalk Forum! I am a forum newb but have been a casual user of Cakewalk products over 10 years now and have been lurking the last several months whilst I get my new studio setup. I am a member of several other forums, and I find that the people here are a bit more helpful and less hostile towards each other than most others, so I am hopeful you guys will be able to help me out on this one.

I have been using a Delta 1010 sound card for the last 4 years, and have been very happy with it's performance. I recently added a second card to my setup, and have started having some issues.

Long story short, I have read the Maudio knowledge base, and have connected the cards clocks together with a SPDIF cable as instructed, have setup up the cards in the patchbay per the kb's recommendations... and the sound cards are working and sound fine, in 16-bit. I've run the wave profiler in Sonar 6, but now I cannot use 24 bit recording or a I get an error message stating that the sound cards can't support it. I've tried various things to debug this, including uninstallating and reinstalling, all to no avail. I am stuc in 16-bit land now.

While I am generally OK with 16 bit/44k recording, which I use for writing and arrangement, I am disappointed that the option to record in 24 bit is not available to me, which I use during my actual performance takes. I have several projects that I am working on in 24 bit, now I have to change formats in order to hear them.

Has anybody else experienced this problem with the 1010, and have you found a fix?

I guess I should state my platform - it is an AMD Athlon 3400 with an nVidia chipset, UMA graphics, and 1GB memory.
