Problem with export_fig - eps2pdf

I keep receiving the following error code when trying to use export_fig for .eps images. I have the latest copy of export_fig, Ghostscript, Xpdfreader/tools (pdftops), and I don't think I'm making any syntactical errors since I can save a .png without error.

Ghostscript error: perhaps C:\Users\-\AppData\Local\Temp\tp0529ef87_f6a2_44f2_bcb9_a061dc5608cf.pdf is open by another application
  or maybe you have another gs executable in your system's path
Ghostscript options: -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -sOutputFile="C:\Users\-\AppData\Local\Temp\tp0529ef87_f6a2_44f2_bcb9_a061dc5608cf.pdf" -dEPSCrop -sFONTPATH="C:\Windows\Fonts" -f "C:\Users\-\AppData\Local\Temp\tp9407d70e_bf3a_43bd_b0f1_b3d1844f732e.eps"

export_fig error. Please ensure:
  that you are using the latest version of export_fig
  and that you have Ghostscript installed
  and that you have pdftops installed
  and that you do not have multiple versions of export_fig installed by mistake
  and that you did not made a mistake in the expected input arguments

If the problem persists, then please report a new issue.

I know it's a bit of a long shot, but I would appreciate any suggestions.

Start with checking the error message:

 C:\Users\-\AppData\Loca\Temp\tp0529ef87_f6a2_44f2_bcb9_a061dc5608cf.pdf

Is this really a "-" in the user name? Does the file exist? Is it opened by another process?

 or maybe you have another gs executable in your system's path

Please check this also.

p = strsplit(getenv('PATH'), pathsep);

Are there several GhostScripts installed?

Thanks a lot for the response Jan.

There is no "-", the file does exist (it's a blank pdf), it isn't open by another process. At least not that I know of.

Sorry I'm not sure what that command is telling me exactly (number of gs executables?), but it returns this:

      'C:\Windows\system32'
      'C:\Windows'
      'C:\Windows\System32\Wbem'
      'C:\Windows\System32\WindowsPowerShell\v1.0\'
      'D:\MATLAB\bin'
      'D:\Downloads\Putty\'
      'C:\Users\username\AppData\Local\Microsoft\WindowsApps'
      'D:\Downloads\TeXstudio\New folder\miktex\bin\x64\'

I have uninstalled/reinstalled gs several times, but have made sure to completely remove it before reinstall. I'm beginning to think it has something to do with miktex..?

You can check this without uninstalling MiKTeX: Only remove its folder from the PATH (of Windows, not of Matlab) temporarily and try it again.

The message "Last OS error: No such file or directory" looks important.
