Tony,
Let me clarify the MyEclipse doesn't provide any intrinsic support for CR Plugin. Please refer -
http://myeclipseide.com/module-htmlpages-display-pid-1.html . Can you answer few queries for me to get to the root cause?
1. Can you copy and paste your installation details? Open MyEclipse IDE, from menu options click on MyEclipse > Installation Summary > Installation Details
2. Can you share a weblink of CR Plugin?
3. How did you add the said plugin? Using Help > Software Updates > Add/Remove Software > Add > Add Site? If yes, can you share the update site
4. Or did you copy and paste the plugin to [your myeclipse installation dir]/dropins/plugins dir?
5. Have you verified that the said plugin is compatible to the base eclipse of installed ME version? For e.g. if you are ME 6.x, the base eclipse is 3.3, whereas if you are on 7.5, base eclipse is 3.4.2, in case you are on ME 8.0, the base eclipse is 3.5.1.
If you have veririfed the said plugin is compatible, I would recommend you a quick fix using pulse. Follow below mentioned steps -
1. Open pulse. If you don't have pulse, download the same from
www.poweredbypulse.com
2. Login to pulse. You can also login anonymously.
3. Choose the relevant eclipse realm from the top left hand corner dropdown
4. From MyProfiles select your MyEclipse version
5. Right click on MyEclipse version and from the context menu click on [Re-install and run]
Pulse will automatically detect any dependency issues.
In case the plugin is not compatible, please remove the same from your MyEclipse profile and restart your IDE.
Hope this helps.
