Not able to use my Hotmail account on my Mac Laptop OS 10.5.

I can sign in to my hotmail acct & see a screwed up page with no emails listed. If I scroll down, I see the last email I received was 11/23. The page is frozen; doesn't allow any activity! I have tried a number of fix-its including installing Firefox as new browser but I get a grayed-out page of choices. Tried doing a different way buy got message saying this was not available to me. I CAN get on Hotmail from a Dell Desktop so this problem seems to be related only to Apple Products! What can I do as the Dell is old & I was about to throw it out! So much for the quality of Apple products! More trouble than they're worth! None of the suggestions offered from MSN, Hotmail Support, geeks, etc  have worked so what now?
