[Help] Reverse Engineering Decryption!

[+cs.tribal]

Here is the riddle:
http://pastebin.com/ixzWFx8g

I managed to find the download link, but you have to find the password for the archive(winrar) file too! I have been trying to decrypt it 2 days now but I have no idea what I'm doing so I had no luck with it!

 

Please someone solve this to me, I know that with some basic knowledge it's a really easy thing to do but damn me, I dont know anything yet about how these things work!

If you manage to find the solution(the password), please send it to me via PM so that not every one can see it!(anti-leeching reasons)

Thank you!
