Dungeon Architect

I recently purchased DA because the vids are so , and I’m just not a TA to make levels. However, I’m finding that DA is constantly crashing the app due to video memory leak, or locks up. Even small actions by dropping a mesh into a theme. If I’m not using DA then no problems, UE run’s smooth. Maybe it’s just the theme builder, but since I need a theme and I can’t make one I can’t tell if there is any other issues.

I upgraded my computer because it died, and I decided to skimp on ram until next month. So I’m only running 8gb for now due to the prices and I’m not made of money :
I’m wondering if it’s a memory issue, or a memory leak. Either way it’s unusable right now. Also one final note, for some reason loading up any UE project even a empty one takes a few minutes. I’m not sure if it’s related though.

I’m using UE 4.20
DA 2.9.2

If anyone has had these problems and may know what’s up(buy more memory?) I would appreciate some assistance to resolve the issue.
