James released 5.6.23 on September 8, 2011 to deal with issues caused by yagc (Yet Another Google Change) to the keyword tool.
For those of you with an AdWords account, JJJ strongly recommends using the AdWords Login integration in Micro Niche Finder. Note that this will work even if Google has suspended your Adwords account's ability to create campaigns.
If Micro Niche Finder and all of its windows are completely closed before installing the 5.6.23 update, a Windows restart should not be necessary.
Registered users can get the most up-to-date details about the most current software version, changes and downloads in the "Important Announcements" section of the Micro Niche Finder software interface.
