Getting "Run-time error '6': overflow" when I try to use DigDB

I have been using DigDB fine for more than a year on my old computer, and now I have a new computer with Excel 2007.

I have had it for almost a month now, and it has been working fine with Excel, but today when I started up my computer and used DigDB, it gave me an error that said "Run-time error '6': overflow". It said that this error was for Microsoft Visual Basic.

Does anyone know why I am getting this error when I try to use ANY DigDB functions? I was trying to sort my spreadsheet when I got the error.

If anyone knows how I can fix this, the advice would be greatly appreciated. Thank you.
