Hi,
<br>
When you install OpenLP it removes the previous version as part of the installation, so all you need to do is to install the released version
If you click on Tools -> Open Data Folder and then browse up one level, you should see a (may be several) folder(s) with a name something like "open-lp YYYYMMDD-HHMMSS" the contents of this folder is a copy of your data folder. Given that you have installed the latest beta and then reinstalled the released version you may have several backup copies so you need to make sure you copy the correct folder back. (If you are using OpenLP on Windows then the default OpenLP data folder location is %APPDATA%\openlp\data (On windows 10 this usually points to
C:\Users</span>(user-name)\AppData\Roaming\openlp\data)
<br>
There are many ways you could proceed, but I would probably open the data folder from OpenLP, close OpenLP, browse up a folder, rename the folder named "data" to "data.old" and then rename the "open-lp YYYYMMDD-HHMMSS" folder to "data" then restart OpenLP.
<br>
Hope this makes sense,
<br>
