Hi
My situation is even worse than you, I landed with my family on 14th July and after completing the formalaties we came back. Now we got only one PR card of my youngest daughter, on checking with the call center we came to know that there is a picture problem and we need to come in person. The letter with all details will send to us as pe given address.
So now I am out of Canada and very tense what to do, I came to know that we need to make the travel documents to re-enter. So waiting for the letter for re-submission, as soon as I will get I will apply for the travel documents.
Our problem is that we have some comitment till December 2011, so very confused what to do if will go and re-submit the picture and again same problem will come than?

?
I hope your problem will be solve soon once you will go to their office, please up-date me as well what is happening with your card.
Wish you all the best,
Take Care
