How do I check that the DLL was instanciated correctly? I tried IsObject() and IsNull() and they both give me an error message.

Can you try to create object using late bindig using such:
dim obj as OBJECT
SET obj = createobject("dexutility.dexutility")
Sometimes it works better than early binding.
