MM7DBT Codeplug Editor

hello All im having this issue with RadioDDity DB-25D
I'm trying to import my extensive Anytone D868 codeplug by selecting the .LST file in a folder containing all the CSV files from the Anytone codeplug. As soon as I try to import into MM7DBT Editor, I get an Unhandled Exception error. In looking at the details for the error, I can't make heads or tails what might be wrong.

I am also having problems . I select the file which is located with all th eexport from the 878. It sits at 10% for 40 mins this time . Last time it was about 30 mins and I had to stop due to other needs.

Thanks
