problems with sprites

hello I am trying to make a weapon system on my first xna game. I was wondering if anyone could help me with a problem I have. Im using the XNA "How to" examples to try and render a simple texture as a sprite. I managed to use the first "how to render a sprite" example to render a sprite. the problem is, but i want to be able to position my sprite where I want so I used the second "How to" example. so I read through the tutorial and got the code in my game but when I run, I get an error saying my texture is being called as a texture2D instead of an AnimatedTexture(the code is made for an animated texture) so i guesss my texture is not animated.. but I dont want an animated texture! I just want a simple one and I just cant work out how to do it.. I found this other tutorial that seemed good but included this weird camera that can be rotated around the sprite... the camera code was buggy and didnt let my code run..

all I want is to know how to render a sprite at a given location and be able to change the variable to move it around.

So Iv been fiddling around aimless, not knowing what Im doing trying to get this sprite to appear. Once I get this sprite rendered I think I might be able to work out a way to get it moving like a rocket or something.

anyway this is my code , can somebody please help me, or maybe point me to a good tutorial.

at this point in time Im getting an error saying

Error 1 'Microsoft.Xna.Framework.Vector3' does not contain a definition for 'ViewMatrix' C:\Documents and Settings\something \My Documents\Visual Studio 2005\Projects\WindowsGame3\WindowsGame3\Game1.cs 133 45 Spaceshooter

this is my code (i know its very messy and some parts are completely useless but hey Im new and Im experimenting with anything I can find, also iv commented a lot of stuff out because I experiment but I dont want to loose the original working partts of the code so I comment them out, add the new code and see how it goes). If someone can help me i will be extremely thankful!
