I downloaded & installed Wow trial, but i cant uprage my account to burning crusade trial account! Can someone help me?

You are trying to upgrade to a Burning Crusade Trial account?  I dont think that exists.  If you want burning crusade then you have to buy the original, then buy burning crusade.

* Standard Trial is for those that do not have World of Warcraft subscriptions yet.

*  Burning Crusade Trial is for those that have a World of Warcraft subscription (and hopefully level 58 or better characters) that would lke to see Outland and some BC content.

*  There is really no point for a Standard Trial to be able to have a Burning Crusade trial upgrade; there is really no significant BC content you can do before level 58.  And, it would pretty much take you that long to get there anyway.

*  And if you are trying to get an 'extra' two weeks by chaining BC Trial after the Standard Trial runs out . . ..

So, if you like WoW, might as well pony up the Gold for it.  Heck, it isn't even that much anymore.  You can start with the main game and upgrade to BC when you hit 58, if you like.

Good Hunting

And dont forget WoW now has the battle chest

• World of warcraft
• The burning crusade (expansion)
• 1 free month sub
• 2 Strategy guides
• DVD (trust me thats a big issue as original WoW was on 5 CD's)
• Only $40

That's not entirely true.  Perhaps the OP wants to play as a Blood Elf or Dranei.  There were other things that were added with BC for below level 58 as well, like jewelcrafting/prospecting for instance.  I'm not exactly sure though whether you need to have the expansion to be a jewelcrafter or not.  I don't believe you do, so that was added to the original game even if you didn't purchase the expansion I believe.

To be honest, you may not be able to play those two particular races, but all of the classes are available, so there is no real need to have BC in the trial.

...oh and yes you would need BC to try jewelcrafting as the trainers for it are in the Dranei and Blood elf areas.
