Hello-
My classmates and I are attempting to use GeoPlanner for a landscape planning and design class, and we are having a pervasive problem with our saved GeoPlanner project files becoming un-openable either days or sometimes only hours after they were created or last saved. When attempting to re-open a project from our respective accounts' "existing projects" menu, the following error is all we receive:

... with error db6dffdece45441e82b0d7c3b65c60de identified but no other explanation.
Please help... this problem in preventing ALL incremental progress on our projects.
Thanks.
