gduerb,
Sorry to hear you are running into this issue. Could you provide below information –
1. Open MyEclipse Blue IDE, from menu options click on MyEclipse > Installation Summary > Installation Details > [copy to clipboard] and paste the same here
2. Clear your .log file located at [your workspace dir]/.metadata/.log, replicate the issue and attach file here
3. Can you open with a different workspace, does that fix the issue?
Sorry for the inconvenience. Let me know how this works for you.
