Microstation not picking up network drive on one PC.

Hello everyone

I have a network drive (named Z:) that contains various .dgn files. When I double click these files on various computers, it opens up perfectly fine in Microstation. However, on one PC it simply says "File [Z:\PSXXXX Prelim Triangles.dgn] does not exist". Also when the drop down for drives appears, it does not show the Z: drive at all. The settings for Microstation is the same for all the PCs as well, and other file types (like Excel files) all open up fine on the network drive.

Does anyone have any idea what the problem is?
