DataGraph version 4.7 was released on the App Store last night. We have had some reports of problems with the version not being verified properly, and reloading does not fix the problem. We have corrected an issue with the verification mechanism and submitted a new version to Apple that will be 4.71.
We hope that will be out soon for any App Store users having this issue. Email us if you are having trouble accessing the program. (help@visualdatatools.com).
