Hi,
I'm afraid it is not possible to restore a CueCore1 file to a CueCore2. Although there are some things the same, others have changed very much in the CueCore2.
I think the easiest way to proceed would be to record the outputs of the CueCore1 in the CueCore2, and create tracks for every recording and cue. You can then add them in the six playbacks of the CueCore2.
Another option is to recreate the tracks using CueluxPro.
Greetings,
