i recently switched from wow matrix to curse....there r mods i use that curse does not have....i downloaded them (lightheaded, epuipcompare and many more) it shows that all the addons r there and all out of date r loaded...but the addons r not showing in my game...i have windows xp....please help

The v3 client does not show addons that are hosted exclusively on wowinterface.com, such as lightheaded. I suggest switching to the v4 client http://www.wowace.com/ (scroll down for the link) which does track wowi hosted addons, but opens your web browser to the download page.

Also, read my answer http://wow.curse.com/forums/t/121949.aspx for an additional tip.
