I recently decided to start speedrunning Portal after playing it for a while. I came to this forum for resources like splits for LiveSplit and general guides. However I ran into a problem with the Autosplitter.

Every time I hit the Activate button in LiveSplit to activate the Autosplitter, it comes up with an error message. There have been two variations so far. The first error message that came up was "The Auto Splitter could not be activated. (Object reference not set to an instance of an object)."

After I launched the SourceUnpack version of Portal once, I tried to activate the Autosplitter again. However the error message now comes up as "The Auto Splitter could not be activated. (The given key was not present in the dictionary.)" I have been unable to find any fixes so far. Can anyone help? Thanks in advance.
