products prices disappear after edit curacy

[thunder2010]

Hello,
My site was working great and i am using price buy attribute and every thing was working good.
I found that i don't need some currency so i made update currencies then delete all other currency and let only USD also i removed the side box for that, After that when i go to see my site i found that all products prices are 0 and when i look at the admin i found every thing ok and all prices are there ??
