pls help.. my Tomcat won't start up anymore..

My Tomcat won't start up anymore..  it's version 5.0.27..  on W2000..

I had to turn it off and on so much b/c every time I compiled a servlet
I had to turn it off and on, otherwise it wouldn't reload, which is a
real pain...  why can't Tomcat reload from a newly-compiled class just
like a browser can reload from a newly-saved html file?  I put this in
server.xml

<DefaultContext reloadable="true"/>

but Tomcat still won't reload stuff from newly compiled classes, even if
I clear cache...  even if I delete a class and hit reload on browser it
still reloads as if class were still there..

now it won't start up again..  I suspect it's from having turned it off
and on again so much, I run startup.bat and the console appears very
briefly tben dissapears.. this has never happened to me before..  :(

would appreciate any suggestions..  thank you very much....  Frances

(I put that same line,  <DefaultContext reloadable="true"/>,  in
server.xml on server where my website is, and it works fine, I hit
reload once on browser and Tomcat always reloads from newly-uploaded
classes w/no problem, don't know why this won't work locally on my
machine..)
