ADE crashed when I plugged my Pocketbook Touch Lux

Hello,

I have a big problem with my reader : I download books I borrowed on digital libraries. But ADE crashed when I plugged my reader to transfer the files. As soon as I unplugged my reader, the software works again.

Some months ago, it was working and now it's impossible : the same with two diferents readers, and I tried with different computers, differents cables ... Our readers are on date, and ADE too.

I have a Pocketbook Touch Lux 2. Pocketbook support says it must be the fault of ADE.

Someone had a similar problem ?

Thank you very much

Sophie
