Stacey,
Sorry that you are seeing issues with MyEclipse.
1. Can you please clarify if you selected ‘no addons’ when installing MyEclipse ? If yes, then try reinstalling by selecting the add ons.
2. Please share the link to the other thread you are referring to. Also let us know what exactly you tried.
3. If you have not tried it yet, please download a fresh copy of the offline installer, verify if the file size and MD5 matches with the values mentioned in the Downloads page and install MyEclipse to a different location.
Let us know how it works for you.
