So that the Community can help you better, we will need to know exactly which Canon camera model you're using. To date, we have not made a camera with the model name "TSi." That, and any other details you'd like to give will help the Community better understand your issue!
If this is a time-sensitive matter, our US-based technical support team is standing by, ready to help 24/7 via Email at http://bit.ly/EmailCanon or by phone at 1-800-OK-CANON (1-800-652-2666) weekdays between 8 AM and midnight ET (5 AM to 9 PM PT) and Saturdays from 10 AM to 8 PM ET (7 AM to 5 PM PT).
Thanks and have a great day!
