Localhost problem


I've tried using WebServerXKit and MAMP but neither work for me.

WebServerXKit won't load up Apache and MAMP won't install the files that were meant to be and thus I can't find my password for mysql out there.

What other options do I have? I don't want to format my iBook and start again, I have so much and it'll be so slow to back it all up.

Please advise
