The path is not of a legal form or not enough storage

Upon opening BI360 Composer the user receives the following "The Path is not of a legal form" or "not enough memory"

Symptoms:

System.ArgumentException: The path is not of a legal form.

at System.IO.Path.NormalizePath(String path, Boolean fullCheck, Int32 maxPathLength, Boolean expandShortPaths) 

at System.IO.Path.GetFullPath(String path)  at System.Drawing.IntSecurity.UnsafeGetFullPath(String fileName) 

at System.Drawing.IntSecurity.DemandReadFileIO(String fileName)  at System.Drawing.Image.FromFile(String filename, Boolean useEmbeddedColorManagement) 

at OneStop.Controls.Design.Meta.MetaHelper.SetBackgroundImage(String filename)

or "not enough memory"

Cannot load background image (see last part of the error message: SetBackgroundImage). There is a setting in Composer making it possible to set a background image in Composer. You might have selected a corrupt file, or a too large file (not enough memory).
