SVN not working

I have used svn before, although the only addons i have gotten to work are PHX and wiremod.
I am using tortoise svn and have looked at multiple svn tutorials. any help?

every addon i try the error is like this, the only difference being the link part

OPTIONS of ‘http://gcombatcore.googlecode.com/svn/trunk’: 200 OK (http://gcombatcore.googlecode.com)

You could try checking TSVN’s support site: http://tortoisesvn.net/support
