Version Control for collaborating with UDK

[Exoaria]

I have no idea what to do next, I've tried everything with Perforce but nobody is willing to help me even if I provide all the information that I have. No matter what I do, I can't get the Perforce login box to come up when I start UDK and I have changed the Source Control to false in the .ini so many times now and nothing happens. I've clicked the small icon at the bottom of UDK to the left of the lighting update, that does nothing.
It's simply not working and I don't know what to do next.

Can someone please give me some help or suggest to me a better method of version control?
Thank you SO much, to anyone who can give me this bit of help.

Open DefaultEditorUserSettings.ini file, and look for the [SourceControl] section. Make sure that Disabled is set to false, and add the following lines below.

PortName=(Your Perforce server address and port e.g. p4.yourdomain.com:1666)
UserName=(Your Perforce username.)
ClientSpecName=(The client spec to use when checking out and submitting files, also known as workspace.)

Hope this helps.
