Over several years and Premiere Elements versions, there is an issue with use of the Instant Movie "Outdoor Adventure" theme. As late as the last version (version 2018), the issue presented with displays of a Media Off-Line message scattered throughout in the Instant Movie. See HERE for full details and suggested user solutions for the problem.
ISSUE
The appearance of these Media Off-Line messages is related to an "outdoor-adventure_s_texture.png" file that is associated with this theme.This is all explained in the blog post which is named PE: Instant Movie Theme "Outdoor Adventure" Glitch and which is referenced above.
For the latest version of Premiere Elements (2019) just released, Adobe appears to have addressed the issue and corrected it. My observations on this matter are described below in the ADOBE'S SOLUTION section.
ADOBE'S SOLUTION
Premiere Elements 2019 Instant Movie/Outdoor Adventure Theme
Result: No "Media Off-Line" messages glitches at Timeline and export levels were found.
My Comments: Using the workspace's Export & Share/Custom, the finished Timeline Instant Movie/Outdoor Adventure was exported as .wmv to demonstrate the absence of the "Media Off-Line messages in the 2019 Instant Movie/Outdoor Adventure.
The Instant Movie/Outdoor Adventure broken apart in the 2019 Timeline is shown in Figure 1 immediately below. The red dot points to the outdoor-adventure_texture.png file which Adobe renamed to replace the problematic outdoor-adventure_s_texture.png file.

*Adobe Premiere Elements 2019 master files are often seen on the hard drive under "2019" as well as "17" headers.
**Work done with Premiere Elements on Windows 7 Professional SP1 64 bit. All the Instant Movie settings were left at defaults, including selection of Instant Movie: Auto Edit and Auto-Analyzer with Apply to: Entire Movie.
