Combine Multiple PDF's in Adobe Acrobat 9 Pro V.9.2.0

For months I've made a habit of using the Chrome PDF Crowd extension to convert a couple of different web pages and then combining them using the Combine button in Adobe Acrobat 9 Pro V.9.2.0. For some reason, over the last few weeks Acrobat has crashed in the middle of the combine process. I only ever use PDF's I created the same day with the PDF Crowd button so I suspect a change was made on the PDF Crowd end that is affecting Acrobat.

Can anyone else duplicate this issue?

Please send us your PDF files to info@pdfcrowd.com and we will look into it.

We tried to combine random PDF files using an older Adobe Acrobat version and it worked well.

Thanks for getting back to me. I'm emailing right now!

This issue should be fixed. Please, convert the web pages again and you should be able to combine the produced PDFs in Acrobat now.

Great thanks! I did the task again and no crashing!
