I have just downloaded Gradient XTerminator. When I click on it, it opens Photoshop CS4, But I cannot find where to enter the trial period license key.
Hmm.... its been a while, but I'm sure that once file was downloaded it had to be unpacked and then the single file was then manually placed in the PS Filter Folder.
Here's where mine is, above the GradX filter thats highlighted
Lester you may need to copy the .8BF file and any other files into the CS4 plugin directory then start Photoshop and it should have found and installed it as a filter file.
