Mesh Normals can't be Calculated

[SigmaEOD]

Having an issue while exporting my model to P3D

I've installed the latest 4.1 version of blender and the latest release of A3 Blender Tools

Here is my error log:

`Python: Traceback (most recent call last): File "C:\Users\alexa\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\ArmaToolbox..\ArmaToolbox\MDLexporter.py", line 944, in execute

Try to delete the addon and re-install it. The later toolbox does not call calc_normal_split anymore if the version is greater than 4.0.
