I've had to trim the file to get under the 512K limit for guest users but there a lot either side of the offending transaction time.
http://pastebin.com/hkMVzj0tFor some reason your Armory has not been in sync. It is stuck at block 425773. To fix this, I think you need to rebuild and rescan the databases. Go the Help > Rebuild and Rescan Databases. Click yes then restart Armory.
FFI. I have been leaving the Bitcoin core GUI running constantly to keep the db utd and provide a full network node, then shutting it down before periodically loading Armory to check for incoming payments and/or send payments (I'm nervous about leaving a wallet with upwards of 50 BTC sitting online all the time). On occasion I have forgotten to close the BTC GUI before loading Armory and thus been prompted to close it first. Also, I have suffered the odd 'unexpected closure' of the BTC GUI which remain unsolved. When that has happened it has left bitcoind running and I've had to shut it down with the OS terminal before starting Armory again.
If you're doing that, might as well just turn off the auto-managed bitcoind. Go to File > Settings and uncheck "Let armory run Bitcoin-core in the background". Then restart Armory. This will allow you to keep Bitcoin Core running while Armory is running. However, in order for Armory to work, you will need to start Bitcoin Core by yourself. If you are using a custom datadir for either Armory or Bitcoin Core, you will need to set command line options,
--datadir=<path> for Armory's and
--satoshi-datadir=<path> for Bitcoin Core.
