To find out if you have CE2000, on the main menu go to Help | About. You can do this in just about all software to find out what version you're running.
In Settings, switch to the Devices tab and select the appropriate device from the Waveform Record dropdown (your UA-1D). Likewise for playback (your soundcard).
Also, reading - or at least scannning - the Help File is often useful to gather a general knowledge about the product.
