If you just got your clix2, you need to do two things before you can get Rhapsody to works smoothly:
1) Get the latest build of Rhapsody Client that is compatible with clix2 (see
here). Your clix2 might crash if your Rhapsody Client is too old.
2) In order for clix2 to work properly with Rhapsody, you also need to install the Rhapsody compatible firmware on your clix2. The latest Rhapsody firmware is v1.16 (as dated Jan. 2, 2007). This can only be done manually (for now as written), please refer to the FAQ on 'How to update firmware on my clix / clix2 ?'. Be sure to set your clix2 in MTP mode after the update.
Also, please note that you will have to sync your songs at least once each month so that the DRM won't expire.
