Looks like FlashcardExchange website has changed something so it stops working. 
Need further investigation. Here is the error log:

Root cause found. FlashcardExchange has changed their API.
"question_image_url":null

I will contact FlashcardExchange to fix the API.

FlashcardExchange support contacted. Here quotes the email:

"""
Dear FlashcardExchange Support,

AnyMemo has been used  FlashcardExchange V1 API to download flashcard for a 
long time.
Today we got a customer ticket about downloading issue from FlashcardExchange:
http://code.google.com/p/anymemo/issues/detail?id=137

For my investigation, FlashcardExchange has changed the API format.
Using this API: 
http://api.flashcardexchange.com/v1/get_card_set?api_key=your_key&card_set_id=14
92997
"question_image_url":null
"answer_image_url":null

It was like this before:
"answer_image_url":""

While AnyMemo is still migrating to the now V2 API, please fix this issue ASAP 
since all our customers can't use FlashcardExchange due to this issue.

Sincerely,
Liberty
"""

FlashcardExchange indicate they patched the issue. However it is more broken 
than before. Now we get this error when trying to search.

I just verified Flashcardexchange has fixed issue. Coupled with AnyMemo 9.1.2, 
it should be fine by now.

Hi,

Many thanks.

I can now download "public" card sets but "Access Private Cards" does not
work.

There is nothing I can't do on AnyMemo side for short term. Once 
FlashcardExchange fix the issue, it will work.
For the long term, AnyMemo need to migrate to their new V2 API. But it require 
a lot of work and V2 API is very new and could not be very stable too.

The private card access is still broken. FE support contacted:

"""
The callback url is recovered now. The  weird thing is that the Signpost 
library AnyMemo is using return an exception when I try to get access token. I 
also got confused by the exception. I need to dig into the library to see what 
it is really doing. Here are some debugging log.

When I try to log in to flashcardexchange.com it lets me log in but then there 
is no way to import my flashcards.

The flashcardexchange log in is still broken.  It seems like Flashcard exchange 
login part will not work without completely rewrite that part to suite the new 
website.

Probably not a lot of people are using FE's upload function. I will remove it 
in favor of Quizlet and AnyMemo's own upload server.

FE upload / private card function removed since it is not working. I don't have 
interest to keep their ownership change.
