PostgreSQL server won't start, corrupt?

Hi I've had a a PostgreSQL 9.3 server running on Windows 7 for several
months.

While trying to diagnose a remote computer's connection problem (through
ArcGIS, grrr), i was clicking through the postgres (data) directory and
opened a couple of files using Notepad but promptly closed them without
making any changes. e.g. "C:\postgres\pg_clog\0000"
and "C:\postgres\pg_stat\global.stat".

I added a line to the "pg_hba.conf" file and tried to restart the server,
but now it will not run!

The messages in the log file are:
2014-10-09 12:59:40 PDT LOG: invalid connection type ""
2014-10-09 12:59:40 PDT CONTEXT: line 1 of configuration file
"C:/postgres/pg_hba.conf"
2014-10-09 12:59:40 PDT FATAL: could not load pg_hba.conf

I am afraid something was corrupted, especially based on the info. here: <
https://wiki.pscs.co.uk/how_to:postgresql_server_won_t_start_due_to_damaged_log_files

What can I do to restart?

Thank you,
Rob
