We have a OS7400 system that we bought in a auction. The system is from 2006 (I checked the warranty info and it started in 2006). It came with no software, so i bought the latest which was 4.30i. Installed it. The cards in it are a 64 MGI, 16MGI, 8x8, SVMI20E and a two 8 trk cards. When we try and install a 16 trunk card, the system does not see it. The same goes with a 8trk2 card. The only card it sees is the original 8trk cards. We've spoken with tech support and they were looking further into but we still have had no luck. Any help.
