having problems using news template

Hi..please I'm using local host. I tried the tab gk5 module as done in the Demo quickstart installation, but it gives me error. Don't know what to do. Then also I tried the newsgk5 latest news module and it also gave me an error.
Same was experienced with the header top banner (the one with the large tiles.up) And it wasn't showing up but the space was taken.... I'm just confused with everything....can you help me out.
Secondly, I tried uploading an image in my k2 component and a three line error appeared. Sometimes it uploads, sometimes the images don't. At some point I was thinking it was the upload limit of 2mb. Then I tried a lesser sized image and still some of it uploaded and some came out as error. Please help me out with everything I'm lost with this template.

Sorry but my crystal ball is malfunctioning... You need to provide some useful information. "Error" doesn't mean a thing :/.

1. my nsp header module doesn't display, even after I have set it up.
2. The nsp tab module too, displays error after setting it up.
3. I can't upload pictures on my k2 cuz it also shows error.

I will copy out the errors, but for now if you know similar problems and have the solutions please help me out.

1. Please do not bump your questions.
2. I don't know similar problems. All problems are usually made by user setups or mistakes. Not being able to see your setup blocks me from helping you.

So please post your site somewhere live for the time being so I can check whats wrong.
