I can't buy one time license because it says invalid date range for year end. I noticed the year end date in the file itself is in yellow and the note says: T2 EDI Efile#001005: Corporate Internet filing for year ends past May 31, 2021 is not available in this version. If I chose year end date prior to 05/31/21, it works, anything past it doesn't. I downloaded brand new software with latest update though. Can someone help?
