Broken links?

Hello,

I bought the Techone theme, but I didnt install the demo content, because I already had a bit of content of my own, and didnt want it to get overwritten.

I have just now realised, that pretty much all links on my page is broken? Like userlogins, add to cart, compare, wishlist and such? Can it be affected, because I didnt upload demo content?

I have tried to configure a little in the liquid files, by inserting javascript:void(0); in herf, but no luck...
