Mail doesnt work in

I got a macbook with snow leopard OS X. I’ve been using thunderbird for quite a while now. The mail application doesnt run. I wanted to write an applescript code that sends me a mail message, but it doesnt work. I’ve tried all the example codes on websites and none work. This is probably cause the application doesnt work. I wanted to sending a message via thunderbird, but i heard you cant. Does anyone either know how to fix the mail problem, or how to send a message with thunderbird without using shell scripts?

Thanks so much!

Model: Macbook
Browser: Safari 533.21.1
Operating System: Mac OS X (10.6)

Anyone? Please!
