2018-01-22 11:50:36 (ERROR) -- BDM.pyc:197 - DB error: C:\Users\Larry&Janis\AppData\Roaming/Bitcoin/blocks is not a valid path
You can see that folder... Windows Explorer can see that folder... unfortunately, ArmoryDB can't... and all because you had to get your Wife involved!
(apologies for the bad joke!)
But seriously, that & symbol in your username is most likely causing your issue. I suspect that the code behind ArmoryDB is interpreting it as something other than "Larry&Janis", depending on how it treats "&" operators (from memory it is generally used as either a bitwise AND or a concatenation operator) which could have some really weird side effects.
If you move your Bitcoin Core data directory to a folder that does NOT contain any spaces or strange symbols ie. "C:\Bitcoin", you should find the error goes away. This may help with moving your data:
https://bitzuma.com/posts/moving-the-bitcoin-core-data-directory/yeah...what are those forward slashes in your path about?
did you fat finger that syntax in a CLI argument?
That's just another difference between Windows and Linux... Windows = \... Linux = /...
In any case, it won't matter... Python seems to automatically take care of correcting the path separators depending on the OS... it's just a debug output "glitch"
