Description Ermengol Bota

2006-06-16 04:06:38 EDT

Today (2006-06-16) I downloaded an automatic update of mylar 0.5.3.core and then eclipse didn't startup.
To solve it I deleteted org.eclipse.mylar.core_0.5.3 from plugin folder and then it worked fine.

hope it helps...

The problem is that you need to install all of the Mylar 0.5.3 features at once, and the update manager fails to do that in automatic updates mode.  You will be able to resolve this by installing by selecting Help -> Software Updates -> Search for new features..  If that doesn't resolve the problem please reopen this bug.  I'm going to make this more clear on the download page.
