Ramin,
I am moving to a new windows7/64bit machine and need to set it up while I look up some of the settings that can not be imported, such as Trac and SVN repositories.
Anyway, at one point I got the error that the license is used on too many machines and most features are disabled.
Are you using single-user or multi-user MyEclipse license? The reason you get too many users logged in issue is if you have preceded the number of users logged in using your license. Make sure you stay within the stipulated limit. In case you are using single user license, ensure that at a time, only one of the system is logged in using the license.
2) While setting up Trac as a new repository, the User ID / password fields are not enabled and I’m not able to add the repository. See attachment. Not sure if related. Please let me know how I can enter both.
Based on your screenshot, it shows anonymous options as ticked. Please uncheck this option. This should enable you to enter userID and password.
