The dev sent them a message earlier so they can take the wallet offline for now while the issues we have/had with f7000 are being resolved.  Also, last time I checked they were still using the 1.0.2.9 version instead of the new 1.0.3.1 so maybe it ended up crashing or couldn't find any connection or something else.

On that note, I would encourage anyone who hasn't upgraded to 1.0.3.1 to do it now
