ArmoryDB.exe has stopped working

Hello,

I am using Armory Version 0.96-beta-a3d01aa722
I am using Bitcoin core version 0.15

Prior to running Armory, I ran the bitcoin core program and downloaded the blockchain. When it was done downloading, I closed Bitcoin-core, waited for the program to cleanly exit, then immediately started Bitcoin armory.
The armory program scanned the transactions and completed the scan, then updated to show the balances for all my wallets. Under the Dashboard tab, it says "Armory is online".

I have the following two problems:

1)When sending bitcoins, after entering the destination address, the amount of bitcoins, clicking send, and typing the password, the program gives the following error message in a pop up window

ArmoryDB.exe has stopped working
A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.

No bitcoins appear to have been sent. The balances in armory remain the same after closing the pop up window.

2) At the bottom right, it says "Node offline" and the number of blocks. Does this mean that armory is not updating blocks from the blockchain?

I have both digital and paper backups for my wallet. Could you please advise me how I could proceed from here?

Thank you so much for your time and help, I appreciate it!
