Ok, i finall got it working.
Downloading the file was a bit of a hassle:
First you have to go to http://www.xnt.info/news.php?id=2591
then select the hyperlink that is somewhere in the middle of the Russian text (underlined). This hyperlink takes you to http://leech.x-forum.info/leech.php?file=Irda2k3.rar
and from there you can download the file. For some reason i could not download it directly from the last link!!
From there it is all downhill:
1. Unpack the zipped file in a folder
2. Run irda_install.inf (right click > install)
3. copy all .inf files to Windows\inf\
4. Reboot
5. Go to device manager and install the ir device
(If it asks you for any files, point to the unpacked folder)
I hope this will help anyone else who has the same problem.
