I have a project here and I have some people working with me, I never had any problem with the svn until now that I added some new people to have write permission on the project, they can see the project, the permission but they just can’t checkout the project I was thinking that would be some mistake they were doing so I created another account (this one) and added myself to project that has problems when I tried to look at the files from tortoisesvn it didn’t work it says “Server sent unexpected return value (403 Forbidden) in response to OPTIONS” but it works with my other account (the owner one) so I tested it on the web explorer, when it asked me user and password I used the one for the test and it didn’t work, I used the owner user and it worked...
they are/I am not using https
I’m not behind a proxy
I’m sure about the user and password
I created another project from this account and I can check it out

btw, I really love this site :) I bet when I’m working on big projects I’ll use this on pay plans
