> CEO and COO said that didn't want to get involved and it was for me and CUXO to sort it out ourselves.

uhm, no. CEO's job is to run the company and this is tearing it apart. he cannot shirk this responsibility.

very sorry you are running into this situation. sounds like the 5 of you were NOT full time up til recently? i would suggest recapitalizing the company if possible (i have no idea how this works) since your nonfunctional CDO probably has a chunk of the company in exchange for not doing much.
