All of my add-ons were moved over. To be on the safe side, I actually made a copy of the folder just in case, but did not have to use that.
Thank you very much for this great software package. I had been using the 2.63 and even with all the loading problems, UNDO issues, I kept using it. Now I upgraded to the latest version, and it is like a huge weight has been lifted, and it is smooth, fast, and very useful. Thank You to anyone who has spent time in development of this great software.
