Hi Noells,
I was in a similar position after Windows XP went AWOL, and I also, have a number of Digger products.
I had heard about a software programme that was able to read 32 bit software on a 64 bit system too, but I purchased a computer and put 2 hard drives on it, one 32 bit, the other 64bit, [1TB each drive]. On start-up, you choose which system, 32 or 64 bit, you want, just like changing users.
Perhaps a waste of money, but then again throwing away Digger programmes that can cost hundreds of dollars each, I thought it was worth the expense. Unless you can be sure that the product you heard about works, I would consider the option I took.
