Resharper doesn't seem to be working

Hi,

I just got a new computer and I'm setting up the environment... but Resharper doesn't seem to be working out of the box as it has done on previous times. I installed it on visual studio 2013 update 4 and it appears on the main menu but it does absolutely nothing. None of the features mentioned here work.

If I click on Resharper Tab and check for license information it says "Properly Licensed". Also, through manual tweaking and some time I got Ctrl+T to work so it looks as if it's not completely dead. But when for instance I try Ctrl+R it says "Resharper_Rename not currently available". And as I said no other features are working, no auto completion, no ctrl+click, no warnings, no indicators...

I haven't found any proper solution on your online documention or someone with the same problem who got to solve it. Can anyone give me some help please? Don't bother to ask for any more info.
