How do I modify Chromium's default data directory?

I believe I somehow messed up my user profile directories with my Chromium installation. Every time I launch Chromium, it tells me:

Chromium cannot read and write to its data directory:

C:\Users\Mark\AppData\Local\Chromium\User Data

It lets me choose another directory, and if I choose C:\Users\Mark\AppData\Local\Chromium\, then it launches fine. I can also add the command line argument --user-data-dir to point to the directory.

However, how can I modify the default (currently C:\Users\Mark\AppData\Local\Chromium\User Data) data directory to change it to the correct one? I don't only get this error when opening Chromium, but also when an application tries open my default browser.

Try creating a directory named "Default" under C:\Users\Mark\AppData\Local\Chromium\User Data and point to it if asked by the browser. See if that works (and sticks).

That directory already exists, when I tried using that directory it just created a new profile at C:\Users\Mark\AppData\Local\Chromium\User Data\Default\Default. The directory that I believe I currently use is at C:\Users\Mark\AppData\Local\Chromium\Default. – Mark – 2013-02-05T05:08:18.297

If you're trying to use a whole new user data dir, you might prefer to just delete (or rename) the current one and then Chromium should create it when you start it up. – MatrixFrog – 2013-02-05T05:14:02.140

I'm not trying to create a new data directory, but to edit the default profile it tries to use when it starts up, and change it to my current profile (C:\Users\Mark\AppData\Local\Chromium\Default). – Mark – 2013-02-05T05:17:39.790
