I first contacted support, unfortunately their advice didn't work (I'm posting it since it may help somebody else):
After looking deeper into this situation, we advise you carrying out the following actions:
1. Open Internet Explorer; go to Tools -> Internet Options.
2. Choose the Security tab and first click on Internet and then on
Custom Level.
3. From the Custom Level button the Security Settings will open up.
From there please reset the custom settings to Medium by choosing
from the "Reset to:" menu Medium and clicking on Reset button.
4. Click Yes on the warning message.
5. Please click OK.
After that, please restart Internet Explorer and also restart the casino client and try again.
The inconvenience might also be about that script debugging might be enabled. For disabling script debugging, you need to do the following changes:
1. Open Internet Explorer, go to tools-> Internet options, select the advanced tab; from under Browsing tick both Disable Script Debugging
(Internet Explorer) and Disable Script Debugging (Other)... then press
OK
2. After that restart Internet Explorer
3. And also restart the casino client
4. and then try again
@zerodegrees...
I haven't changed anything so I doubt it. I have AVG, do you have any idea which setting to change?
@VorpalF2F...
Tried running it as administrator but didn't work.
So I'm still out of the game
