Before posting what should resolve the issue, I need to say...Please, Please, Please report any issues like this to Autodesk. If you're on subscription, please e-mail them the issue. If you aren't on subscription, please talk to your reseller and have them report it. When I talked to Autodesk about this issue, they've only had this issue reported to them TWICE. I had two in one day and obviously there's more than cases than that out there. These groups are great for getting answers, but if there is an issue with the product, they need to be reported...not just discussed on the discussion groups. Okay, I'm going to step down from my soapbox now. 🙂
Hopefully this may help the situation a little. I had two people call into our support with this same issue, which I could not produce on my end. A call (for me being a reseller AE) into Autodesk produced a response of...
"...need to do a clean uninstall ACA and also uninstall .NET versions. Then, reinstall ACA and let it install the .NET. Also, if they used the Migration Assistant, do NOT use it again with the new install."
The clean uninstall and reinstall did the trick of fixing the Mtext disabling/graying out the Ribbon as long as the Migration of settings wasn't used. A new install on a separate computer worked out just fine as well, again without using the Migration. Also, if you install the .NET versions directly from Microsoft first, the installation should go much quicker.
Below are the steps given to me via Autodesk. (which were derived from - http://usa.autodesk.com/adsk/servlet/ps/item?siteID=123112&id=9700956&linkID=9240657)
Use the steps below to uninstall ACA 2010 fully to allow for a full clean reinstall.

After an uninstall / reinstall, text editing has become very interesting! See attached file which shows the ribbon taking 90% of the screen.
