I am having the same issues. There is an update available this morning but it takes me around in circles. I can only open the program if I say "No" to the update.
I spoke at length (1 hour 50 minutes) on Tuesday to a Customer Service representative who was speaking to another "more knowledgeable" person at the same time - I shared my screen with them - they redid everything I had already tried and nothing worked (I am claiming 100% of the T3). I have a net capital loss, but the capital gain from Box 21 of the T3 does not show up on line 68140 of the T936, and therefore I cannot Netfile. The Customer Service rep was ALMOST as frustrated as me. Her words - "there is an ongoing investigation" "it is a product defect".
I am almost relieved to know it is not me - I have spent hours on this and I've been questioning my own intelligence?!
