[news.eclipse.newcomer] URGENT: Eclipse won't start

[alain.desilets@xxxxxxxxxxxxxx (Alain Désilets)]

PLEASE HELP! I'M UNDER A VERY STRICT DEADLINE

Been using Eclipse for 6 years with very few glitches.

Suddenly, when I start Eclipse, it won't and tells me to look in the log 
file.

See below for the message I find in the log.

It seems lot of people experience this problem:

  http://tapestryjava.blogspot.com/2004/10/worst-eclipse-crash-ever.html


And the solution that seems to work for most people is to remove this file:

\.metadata\.plugins\org.eclipse.core.resources\.snap
and
\.metadata\.plugins\org.eclipse.core.resources\.root\.markers.snap

But I have neither of them!

I also tried the Workspace Rebuilder listed on this page:

  http://www.eclipse.org/eclipse/platform-core/downloads.html

But when I run the command line:

 eclipse -application org.eclipse.core.tools.restorer.application

I see the Eclipse splash screen for a few seconds, then it goes away. If I 
restart Eclipse after that, still crashes. I also tried the -data option:

eclipse -application org.eclipse.core.tools.restorer.application -data 
myworkspace

giving it both the name of the workspace ("eclipse_workspace" in my case) 
and the full path ("D:\Documents and Settings\Desiletsa\My 
Documents\eclipse_workspace") and neither of them did anything.

What can you suggest. 

Thx
