Problem installing Painter Essentials Ultimate Brush Pack Bundle Volume 5

Hello, I buy Painter Essentials Ultimate Brush Pack Bundle Volume 5 but for this a bad problem happens. 

The Volume 5 is not downloaded by Restore Purchases and is still available for purchase from the Store on opening window of Painter Essentials 8, and does not appears in the library. 

I uninstalled and reinstalled Painter Essentials 8 and all Volumes multiple times, I also deleted the Corel folders remained on pc and the temporary files and restarted but the problem persists. 

Today I was able to download and then install Volume 5 from the link that Corel support sent me but the situation has worsened further: my Painter Essential 8 doesn't even open anymore! 

I have tried to restart my pc several times but the problem is always existing and now I’m uninstalling and reinstalling all again, but I don’t know how to do for volume 5. 

In the Restore Purchases for the Volume 5 always a red cross appears instead of a green and then when I do the Volume 5 manual installation Painter Essentials 8 no longer opens! 

What can I do? 

  • I update because I think this can be useful to someone. 

    After several attempts I have solved in this way: 

    - I uninstalled and reinstalled Painter Essentials 8 again and then I first manually installed the Volume 5 and I have run the Restore Purchases after. 

    - I closed the program and when I reopened it I held down the shift key to be able to reset it to factory conditions. 

    I also discovered that the last brush of the Whimsical package does not work, although I select it then it writes as if the previous brush remained selected. 

    When I close and then reopen the program leaving that brush in use happens that I have to reset with shift key to be able to open it again. 

    I think that this maybe can be a bug in the Whimsical brush pack.
