I would say chances are some configuration files have most likely been altered one way or another along the lines. I take it OScam is turning green in the Sofcam Manager plugin when you select it? As long as it is if you FTP in have a look at the oscam.conf file and see what the settings are in there plus what other files are in there then that should hopefully point us to what's going on, usually something simple. I can't remember for sure on this image but the OScam files on the later build were in /var/key so try there or /usr/key and chances are they'll be one or the other.
The alternative of course is to reflash the image or even move to the little later one. I have this if it's not around here already I can upload. Looks like loads of great things to come extreamly soon with these and official OpenATV support now, but right now probably worth holding off another week or two, so if you want me to upload the Lavatronics OpenPLi Backup here I can do, that comes with a PDF that explains amongst other things how to access the OScam webif, also comes with a guide to flashing E2 firmware via Spark and the Spark plugin pack you need for this if you don't already know about how to do this.
