I installed yesterday a new update of the Unibet software. Maybe that helps to fixed the problem.
You can find the software here. Hopefully this helps to fixed your issue with the software.
Otherwise you can always try to contact Unibet support.
It’s a possibility. I had in the past also problems with the Unibet software and I fixed it, because I had problems with other Microsoft programs that used Internet explorer.
If I remember it correctly I fixed it to go to ‘Internet options’ in Internet explorer browser and than the tab ‘advanced’ and than you click on ‘Resetting’. Than you get a new window and than you click again on ‘Resetting’ and than my problem was solved. Hopefully I translate al menus correctly because I use Dutch version of Internet explorer.
