I've tried to move the dataset_SE and dataset_US to a network server. I've pointed TFDIR and TF_dataset to a new location in my standards.cfg. When I start "AECOsim in MicroStation mode" (gray logo) it works great, but when trying to open a file in AECOsim Building Designer it does not. The file opens briefly, but then it reads "Reading section" in message center (see screenshot) and the program crashes.
There was something wrong with the shapes.xml file at the Organization-level. After deleting this file, now there are no crashes.
