I'm running Kubuntu 12.10 and I need IE8 with ActiveX for a specialized website which heavily makes use of ActiveX

So far I added the custom wine-repository (ppa:ubuntu-wine/ppa) and installed wine 1.5.20 from there. Then I downloaded the IE 8 Installer as it is linked from the entry in AppDB and installed it, which worked just fine (no errors/crashes etc.).
Then I ran Wine, opened the explorer, navigated to iexplorer.exe and started it. The windows comes up with no errors. It says connecting (probably trying to open the startpage), but no page is displayed. I can open up new tabs and enter an URL, but they also stay with a blank page and "connecting...". I can open the context menu (right-click), but no action upon selecting are performed. Also I cannot close any tab. So IE8 is not usable.
So my question, is there someone willing to help me tracking this down and get to IE8 with ActiveX to work in WINE?
This is my very first experience with Linux and Wine, however I do have basic computer/software knowledge.
I would greatly appreciate a positive response.

PS:
I have access to a Windows XP 32-bit machine with IE8, which I could run test on with Process Explorer, Process Monitor which I have already used. I could also copy files (dll's, whatever) from there.
