It has been perfectly solved after updating to ver1.91. Thanks a lot!

Thanks for your great software. However, the error message "error reading file: 'MyFrame' object has no attribute 'usage_tracking'" keeps appreaing when I open xlsx files (or kfit format). It doesn't appear when I first drag Avantage files(Vgd or avg) into your program. Plus, I found that the error doesn't happen when I use older version (1.80_26c01). Would you let me know how to fix this bug?
