Htmltools.exe does not to do the RTF to PDF conversions

I just purchased HTMLtools.exe and am currently testing with it. In my processes I sometimes have the need to process some very large RTF files. 42+ mb consisting of 4000+ pages. I am getting an error in the CMD window:

unknown extension for D:\EDS\PDF\EMLAUTOSNB.TXT.60857_58320_276.pdf'

This is repeated many times until the process ends,
++++++++++++
unknown extension for C:\EDS\PDF\EMLAUTOSNB.TXT.60857_58320_276.pdf'
unknown extension for C:\EDS\PDF\EMLAUTOSNB.TXT.60857_58320_276.pdf'
[Message] Conversion time = 62734ms
[Message] "C:\EDS\RTF\EMLAUTOSNB.TXT.60857_58320_276.rtf" ==> "C:\EDS\PDF\EMLAUTOSNB.TXT.60857_58320_276.pdf'", result=ERROR
[Warning] If the conversion is fail, it may caused by permission problem, please run a CMD window by administrator privilege, and run same command line to try a gain. htmltools.exe is only require administrator privilege at first time when you run it.
TickCount = 62734ms(62.73s), Result = 0
++++++++++++
I am running the cmd window as Administrator as suggested in the error message.

Is there any other things I can try to successfully convert these larger files?

Customer
-------------------------------
I have an update on this. I rebooted the server and now this file is converting successfully. I guess you can close this, I will reopen if it continues
