Display error - out of memory

Hi All,

Using Karamba, I am currently in the process of designing a footbridge to the Eurocodes. The structure is relatively complex and is therefore subject to a significant number of different loads. I am applying loads to the goemetry using the "Loads (Karamba 3D)" node. The majority of loads are being applied as mesh loads. 

Whilst inputting these loads I have encountered the following error message:

This has turned a number of the "Loads (Karamba 3D)" components into the below:

Has anyone encountered this issue and have they found a solution (that ideally doesn't involve simplifying the model)?

For background; I am using Rhino 7 and have Karamba 3D version "2.2.0.12-220322 for Rhino 7" installed. I have a professional license which is valid for commercial use. 

Any help would be greatly appreciated!.
