TortoiseSVN: SVN Checkout won't function?

I don’t have any deep knowledge about SVN or anything, but I pretty much know its purpose; however, after installing wire through TortoiseSVN, it will not install anything else. I create a new folder in addons where I wish to transfer the files and I go to the option “SVN checkout” but it does not do anything, no matter how long I leave the damn thing up. If anyone has encountered a problem like this and fixed it, could you please tell me what’s going on? Thanks.

put an SVN url where it ask’s then click go. When that is complete and you want t update again there will be an option “Update”.

I do put the URL in the designated box but it never transfers the files…
