Another OLCI problem

Been trying to check in for my flight to Dubai tomorrow.
Booked via VH and flying Man > LHR (BMI) and then LHR > DXB (VS)
Already OLCI with BMI this afternoon. I have tried OLCI for the VS flight but keep getting this message:
quote: Sorry we are unable to continue with your Check In. Please go to the Virgin Atlantic Tickets and Support Desk for assistance at the airport.
I have phoned VS and first time got Indian Call centre who told me there was a problem with security, couldn't tell me more over the phone.
Tried again, this time Indian Call Centre told me there was a problem with Man > LHR part of booking, as VH had not booked it, therefore I had to speak to VH to resolve.
Spent neatly an hour on the phone to very helpful lady at VH who kept speaking to someone at VS, who has told her there is no problem with my booking, but still very worried.
Can anybody shed any light on this - please
