Axon software version issues

I have 14 axon servers controlling a 360 degree video wall and we have over the past few months been getting some of the servers serviced. Recently we have had 2 servers come back with software versions 2.1.0.2626 and firmware 2.0.5.165. The servers have been going out with software versions 2.02.2453 firmware 1.4.0.26.

I am seeing allot of content read errors with the newer software version. We had the work done at4wall and I have spoken with them but they say that since its a content error they can't help.

I am wondering if anyone has an idea of what I can do besides redo all the content. It's mostly .png files but there's 100s of them. Can I down grade back to a version that matches the rest of my servers? Any help would be great. Thanks
