System Exception AND Error Loading Map?

[BlueTressym]

Hello.  I've been having problems for a few days with the game crashing frequently.  I thought it had stopped after I replaced a few other applications that could have been memory-hogging.  However, today, after having played for a few hours, I exited to the Main Menu screen to go and do something else AFK, and when I came back to loading, it gave me 'Error While Loading A Map'!

The investigating I did to try and resolve the crashing suggested it related to memory problems; computer stats are as follows:

Windows 10 Enterprise, v. 1703
Processor:  AMD A8-6500 APU with Radeon(tm) HD Graphics 3.50Ghz
RAM 8.00 GB
64-bit Operating System, x64-based processor
Graphics Card:  NVIDIA GeForce GT 610
