Thank you for your suggestions. I've reached out to the local VW team and they resolved the problem via TeamViewing session.
The source of the problem was that the program was installed on a Case-sensitive disk. This is a re-occurring problem with iOS devices.
For VectorWorks to operate smoothly, it has to be installed on a non-case-sensitive disk.
My problem is now solved, thank you.
