Problems installing filters into my Filter Forge 8.0

Hi there

I wonder if someone can help me please.

I have just purchased Filter Forge 8.0 this morning but having trouble installing filters into it.

This is one I am trying to install: Hall of Frame : Vintage feel
https://www.filterforge.com/filters/14020.html
When I click on 'Open this filter in Filter Forge' I then get this error message:

--------------------------------------------------------
Filter Forge not installed or cookies missing in your browser
To open this filter, you need to download Filter Forge and install it on your computer and make sure cookies are enabled in your web browser.

If Filter Forge is already installed, please follow these steps:

Click here to activate Filter Forge cookies and return to the filter page.
Try to open the filter again.
If asked, allow the browser to open the filter with the Filter Forge application.
--------------------------------------------------------

I am not sure what to do now, can someone please help me.

Thank you!

Take care,
Julie

Julie
