I changed over to the new mail 3 weeks ago and since then have been unable to send, delete, open mai

I have been unable to even check my mail for almost three weeks. I tried switching back to the "classic" mail but I can't even do that, everything comes up as an error (javascript error on page to be exact). I am ready to toss my computer out of my window. What is the deal with the incompetency which is the new yahoo mail?
