It seems that the latest version of Comodo Internet Security (V5.x) is blocking access to Filter Forge - a plugin/standalone tool for Adobe Photoshop and texture creation. FF2 worked with the previous versions.
To fix this issue and allow FF2 to load properly, do the following:
- Go to the Defense+ tab in CIS
- Select “Execution Control Settings”
- Click on the “Exclusions” button
- Navigate to the FF2 folder on the left-hand window and move the “bin” folder to the exclusion panel on the right
- Apply and voila!
