From where are you downloading these ebooks.
It sounds like they are not compatable with your Sony.

I have a Kindle and I can not download from Barnes & Noble because ththeir Nook has a different format.

I've had the same problem and was told by an Amazon customer service person that the Archos 7 Home Tablet must not be a recognized device. I've brought the issue to the attention of Archos technical support and they claim to know nothing about another companies software and could not help. I don't think there is a solution, I think it just doesn't work on this device. I don't know why they included the kindle e reader app if it is useless on this device. I also rec'd Syncables 360 software and I can't get it to work either and technical support for that software is non existent. I tried calling the phone number a couple of times and was disconnected each time. I will be contacting the company I purchased this from to log a complaint.
