I have tried couple of ACS cards with both patches 91 I and 91 J and still having problem with loosing the programming after power loss, so I just wondering if its just me or someone out there having the same problems .I tried more than 10 ACS cards originally was 91E version upgraded to I then J . Some of them when it’s upgraded it take about 5-10 minutes to loose the programming and some will loose right away except the time date will still be correct but everything else is gone.
