Internal Ghostscript error

Hi there,

Am trying to use PDF Creator to create and merge 166
documents into 1 (for a print driver mailing application). Every time I
try the individual letters get created and when I try to merge into one
and save I get the following error:

PDFCreator was not able to convert the document, because an error occured:
Internal Ghostscript error

You can find additional information in the log file.

I am using V 2.0 on Windows 7.  #

Log fie:

2015-02-11 13:06:36.4771 [Error] pdfforge.PDFCreator.Core.Jobs.GhostscriptJob.RunJobWork: Ghostscript execution failed:

2015-02-11 13:06:36.5707 [Error] pdfforge.PDFCreator.Core.Jobs.AbstractJob.RunJob: Executing Ghostscript failed



Any
ideas what the problem may be? I have reinstalled the software, also
uninstalled and rebooted and then installed (all with no joy).

Also got the same message when tried to merge 6 documents so not the number of documents causing the issue.

Any suggestions would be gratefully received
