Looks like the session.save_pa th is invalid.

The sessions are saved into this path on the server. If PHP does not have access to write to the directory you get this error.

By the look of the error, you have already made a directory for the session data ('C:\sessiondat a\'), but PHP does not seem to have access to it.

Try changing the folder permission so that PHP has access to it.
If you are having problems with this, try giving Everybody full access, if only to see that this is really the problem.
