Do you still have SE available? If yes, I would open in SE, consolidate all the audio back to zero and export(then import the audio into a PT First session). If not, you could try creating a blank session in PTF and try to Import Session Data and bring all the tracks into a new session. wish I had more to suggest but I've been on the full version and am not clear on the limitations of SE or FIRST. They are both "teaser" programs designed to get you to buy the full version
