File problems and reporting issues

Error messages explain why an operation could not finish. A failed save leaves the drawing open so you can try another destination.

Opening and saving

Check that the file exists and that you can write to the destination. Redline opens .wpr project files; renaming another file to .wpr does not convert it. Unsupported project versions cannot be opened.

If saving fails, check the reported path and error, or save to another location.

Images and output

Image import can fail if the data is invalid, empty, too large, or unreadable. A font may be invalid or may not allow embedding. The error message gives the reason so you can fix the source or choose another asset.

If the platform file picker is unavailable or does not support the output you need, choose the built-in picker in User Preferences....

Reporting an issue

Include the application version, what you expected, what happened, and the shortest steps that reproduce it. Mention whether the problem appears on the canvas, in an export, or both, and whether it persists after reopening.

A screenshot can show a layout problem; a project copy can help reproduce it. Remove private information before sharing. Do not include account credentials or local license files.
