Apar,
I always keep a fresh copy of Aces High/Settings and Sights on a floppy or CD and on my second hard drive. It makes it so easy to do a reinstall or transfer to a new puter or hd. That will include your video settings, stick settings, keyboard mapping, head positios, and convergence settings. Whenever a new patch comes out, I dl the full version and store it somewhere in case I need to reinstall. Then I do a fresh isnatall of everything includings Mitsu's latest sound pack after deleting the Aces High/Sounds folder. IMHO it it always better to do a fresh install rather than copy new onto old, preserving any corrupted files you might have.
