Hi there,

Sorry to hear you are having problems.   Portrait Professional has been tested against photos your size and larger and works ok.  The most likely explanation at this point is that there has been a problem with loading Canon raw files, which results in your picture taking up more memory than it should.  We have an improved raw loader for both Canon and Nikon raw files that can be downloaded for free from these links:

Canon and Nikon Raw loaders for Portrait Professional (Windows)

Canon and Nikon Raw loaders for Portrait Professional (Macintosh)

Would you mind trying that to see if the problem is fixed?  If not, the best way to proceed is to open up a support ticket.

Thanks for your patience,

Tony
