I am one of the Flash Chat users and have it integrated with my forums. I did have issues installing and integrating after UBB 7 came out. There is a "fix" for it but my memory fails me at this present time. I'll see If I can dig up my notes in the next few days.
THis is a shame. I think it works well and would love to see some support from them but I recall having the same experience as you Giz.
