clear the CalcCache
In general, if an error occurs with a running a GeoDMS project or re-opening a current configuration, we first advice to clear the CalcCache folder. This advice only applies to GeoDMS versions before 8.001 as the 8 serie does not make use of a CalcCache anynore.
In project using large amounts of RAM memory, in relation to the physical amount of memory of your machine, memory allocation errors can occur (sometimes even resulting in application crashes). In these cases, it might help to disable the Multi Tasking option 2 (From the GUI go to Tools > Options > Advanced). Be aware that calculations will become slower.
