Why did you post this in the forum for Adobe Reader?
Because one of the suggested answers from Sony was that I needed to increase the allocation of Adobe ID authorised downloads and I couldn’t find any reference to these limitations on Adobe’s website, nor could I find a way of increasing the authorisation.
The original post was to the Adobe Reader forum, and was:
"When downloading an adobe drm epub book the message Maximum number of
updates exceeded - error code:-40337(400) appears. What do I do? This
relates to the Sony ereader software."
When asked why he posted to the Adobe Reader forum, the response was:
"Because one of the suggested answers from Sony was that I needed to
increase the allocation of Adobe ID authorised downloads and I couldn’t
find any reference to these limitations on Adobe’s website, nor could I

There's no statements about the use of Digital Editions or Adobe Reader in
this sequence. The error message is not from Adobe software. And what's a
'update' in the first place? Also, there's nothing in the original post
that says the attempt at downloading the ebook was to download it into
The 'tech support' for SONY referred the poster to Adobe because he was
supposed to 'increase the number of authorized downloads' (in Digital
Editions?), which doesn't correspond with 'updates' I don't see any link
at all. So, the way I read this one is that SONY Tech Support is telling
the poster that Adobe authorizes the downloads from the SONY Reader Store
to his SONY ereader.... That's not true. And Digital Editions has no
limit on 'downloads', nor has it been updated via downloads from Adobe's
The SONY Bookstore relies on Adobe's Content Server Manager software to do
its digital rights management. That's the only cross-tie or common
thread I can find here. My conclusion is that it's not a Digital Editions
issue at all. Sorry we can't help you.
