Simply Accounting Pro 2006 Release C or D = can anyone send/supply or direct me to a copy of this - many thanks in advance

I have a client who uses this version, they will move up, however their machine was in a critical state and the data has just been recovered and the release packs are missing. I need get simply 2006 pro back running again, unfortunately they only have the install disk which is Release A. The upgrade path for their version is approx $500.00, so getting this back to where it was in the meantime is a big thing for them.

Many thanks for any support you can give
