I would keep an eye on it and check that the 'progress' is changing to make sure.
Another way is to go to 'results status' over at your WCG 'My Grid' section, identify the unit and see if any of the others in the quorum have completed and see how long they took
No problem mate - you normally find with these that someone else has previously reported a similar problem, and if you go over to WCG and look in 'Boinc Support' or the relevant project support section then the solution can be found
