You can get the current latest NoteCaddy build from*http://www.assaultware.com/notecaddy....0.zip.**(when a newer version is out you can replace the version number in the link)
It can be installed by closing HM2 and unpacking the .zip file into*C:\Program Files (x86)\Holdem Manager 2.
You will likely want to reset and reprocess their notes in NoteCaddy after making the update.**http://wiki.assaultware.com/How-to-r...ddy-notes.ashx
The builds that are not included by default with HM2 are not thoroughly tested with HM2, so there is a good chance there will be issues. If something is not working for you in the default NoteCaddy that is included in HM2, you can try updating to a newer version by following the method above.
