t2 returns for 2000 to 2006
I am trying to complete and file T2 returns for the years 2000 to 2006. I cannot start preparation of 2000 or 2001 . For 2002 to 2006 I can prepare them and am using web access codes but i get an error when filing that software package does not support the filing period.
Why am I not able to even prepare the 2000 and 2001 and why am a I not able to file the other years through efile when CRA has given me the web access codes for each one?
