why i cant sell stuff?

im new anyway i know that we can sell stuff to the Rune trader, but i cant anymore, it show when i press "sell" a mesage "belts" or bags empty. (but im not empty). So what is happening?

go to a merchant not a rune trader and try it

As the other poster said. A rune trader can only buy runes from you. A merchant can buy everything that you want to get rid of though. But do not sell things like dye, runes, inscriptions, or scrolls to a merchant as he will give you pennies compared to what a dedicated trader for those items will.

Mega Mouse

i have other novice questions
- i saw we can make 4 chars in the account, but we can delete one char without affecting other chars?
- i have celeron 1700, radeon 9950 and 520 RAM and while playing GW nightfall my CPU usage is 100% (even if all options are low-one black ball for GW progamers, cuz i have the minimum requrements). The game is little slow, but is playable, strange.

So is a problem if i play hours this game with this 100% comp. usage? i tried in vain to set even my video card options to reduce this high usage.

Yes you can delete a character and leave the others. Sell / salvage all your customized things and stuff everything else including gold into the account storage first.

100% is normal

I use 100% on my CPU and it's 2.2ghz. (I also usually have GW, IRC, iE and Ventrilo all running at once.)
