Would you mind to try "Rebuild and Rescan Databases" you can find it on "Help".
I am sat at preparing databases & the boxes greyed out in Armory, how do I send a log file? is that from Bitcoin Core or Armory?
You can post the logs here or pastebin.com and it should be the armorylog.txt
You can get it by opening the armory wallet then file --> export log file.
I don't know what OS you are using but alternatively, if you are using Windows here's the folder location below
C:\Users\<YourUsername>\AppData\Roaming\Armory\armorylog.txt
For Linux:
/home/<YourUsername>/.armory/armorylog.txt
