|Ok, so Skype can't be the issue.|
I assume, you're playing the online game, by using Internet Explorer.
So why don't you simply reenable the add-on in the settings of the Internet explorer.
In doubt, enable all add-ons listed in the settings of the Internet Explorer and try, whether the game is running fast.
If it does, disable the add-ons you think, you don't need.
Do this step by step and always retry loading the game.
Trial and error, you know.
