How to revert to the facebook chat application to the old one

Most I.R. impacts require grease in the hammer mechanism (clutch) and oil in the air motor.
To lubricate the air motor simply add oil through the air inlet about 3 to 6 drops at every use.
To lubricate the hammer (clutch) mechanism you will need a grease gun with a needle, the grease fitting (item# 17) is located on the hammer case assembly (item# 15) 2 or 3 small squirts will sufficiently lube the hammer (clutch) mechanism.
With heavy use grease the tool once a month, with light use 2 to 3 times a year.
Follow this link for the parts list, also indicates the grease needed:

On YouTube just use ProxTube, Greasemonkey and this script: http://userscripts.org/scripts/show/39167

On vevo only with VPN and special tools for mac for example: Jaksta and on windows use URL Snooper to get direct link

To download themes for XP and vista, you'll need a few things.

Firefox Web Browser - http://getfirefox.com/
Greasemonkey Firefox Addon - https://addons.mozilla.org/en-US/firefox/addon/748
ThemeXP.org Link Rewriter - http://userscripts.org/scripts/show/5150
UXTheme.dll Patcher - http://www.neowin.net/forum/index.php?showtopic=140707
WinRAR - http://rarsoft.com/

Install them in that order. Once they're installed (you probably want to restart), visit http://themexp.org and download a visual style (theme). Extract it to c:\windows\resources\themes and it should show up when you right click on the desktop and go to properties.

StyleXP helps this process a bit (you won't need to install WinRAR or the UXTheme patcher). It does, however, cost money.
