thank you!!!! this seeems to resolve the problem. i just tried on a brand new toshiba laptop, same problem after clean win and opera install; but with the parameters:

launcher.exe --with-feature:"mse-h264-support"=off

its working again

I'm at work right now. Opera is working fine with win7 sp1 x32. as i can see everyone is on x64 with this problem.

I dont have a screenshot right now but others from the forum posted this:

It looks the same for me too..

I have the same problem.

Hello.

This is my first post so go easy on me. I've been using opera since version 6-7...
Everything was okay until now. The version 30 stable was released and since then opera only opens up and nothing happens, nothing works. The menu, and the tabs up appear but nothing works, speeddial doesnt load, only blank white screen.
I've tried uninstalling, uninstall with deleting all my settings.(i have them saved), Uninstall it uninstall software, manually removed all the folders from app data, roaming. and if i reinstall it the same problem appear over and over. I've tried the web and the offline installer too. Tried to reinstal version 29 it is working okay, but when i close it it updates itself, and same thing...

I've tried compatiblity mode too. I have a Sony Vaio laptop with i5 cpu, 8GB ram, nvidia gt330 graphics card, win 8.1 x64. i can post screenshots to if needed
Any advice?
