Robohelp 10 crashing when generating a CHM

I am running Robohelp 10.0.1.292 on a Windows 7 64-bit with 4GB of RAM. I have a Robohelp project with 1,969 topics from which I've successfully built three WebHelp outputs, but when I generate a CHM file using the same conditional tags as one of the WebHelp outputs, Robohelp consistently crashes on the same topic and produces two crash events in my Windows Event log:

Event #1

RoboHTML.exe

   10.0.1.292

   51493787

   mfc100u.dll

I rebooted my PC and restarted Robohelp, then applied a conditional tag to exclude the topic from the build and was able to successfully generate the CHM file. I turned off the conditional and have tried the following strategies which all result in the same two sequential Robohelp crashes:

• Delete the CPD file
• Delete topic from project and recreate it
• Delete all the links to and from this topic
• Remove topic from the TOC
• Turn off conditional expressions
• Delete the browse sequence
• Delete the index
• Change the path of the CHM file to one that is outside of the project
• Shorten the output path of the CHM file to not have any spaces

Any insight would be greatly appreciated!

Thanks,
