This reply is probably too late, but I did this HIT earlier tonight. The second chat went fine when I took it. The whole thing took about 40 mins. for me (but there was supposedly some chance for a bonus or something - I don't remember exactly). Maybe if you contact the requester, it can be resolved somehow. Good luck. It sucks when a survey crashes that you've put time into. It has happened to me before on other occasions, so I know the feeling.
