The Edgeman

I have been screaming/yelling about two and half years ago, without any proper technique. After a few months I stopped due to pain in my throat. Today, everytime I try to scream or sing with some grit (of course, with the correct techniques) I still have the pain back for like hour. And if I sing loud and clean for like fifteen minutes, I will have a vague pain.. Can somebody help me to recover this or suggest me what to do?

Can someone share with me some free-ways to download on the PC some bundles of bits for Cubase? I really wanna try out and learn how to make music with the Cubase 5, but I don't know where to find some freeware. Thanks a lot!

Hello, I am trying to find a suitable chord for Am, C and Em. It is a four-chord song, so if you could give me something handy, I would be pleased. If possible, please share an easy chord, as I am not really prepared yet to make masterpieces on my guitar. Thanks a lot!
