I'm currently using version 2.2 with powerpoint import capability, i've downloaded version 2.3 but when unzipping it says i have to delete current version first - will this delete the powerpoint import capability, how do i best proceed ?

PowerPoint Import Pack needs to be upgraded too to work with version 2.3. Therefore:

1. You need to download new version of PowerPoint Import Pack (using the same personal download page as before - the link is active). If it is missing, please contact us at support@courselab.com.
2. Remove PowerPoint Import Pack and CourseLab 2.2 using Add/Remove software
3. Install new CourseLab version
4. Install new PowerPoint Import Pack (using the same serial).
