Using Streets & Trips 2009 maps with 2007 program?

does anyone know of a way to use s&t 2009 maps with s&t 2007 programs - seems to be numerous problems with 2009 programs - i'm currently using 2007 and am happy with it but would like to utilize latest map data if possible -thanks

I was just thinking of the same thing. Since installing 2009 in my desktop, i have had quite a few problems. I get frequent lock-ups and ocasionaly the program will just shut down completely. No warning messages or anything, it just disappears and my screen goes back to desktop. I don't dare install it on my laptop, with it's much smaller hard drive and memory. I'm going to Mexico this winter and would love to have the expanded Mexican maps but I think I will go with my 2007 version that I know works. It would be great if one could import the newer map data but I guess that would not be possible. Too bad MS doesn't just offer an updated map data base for their earlier programs. I would gladly pay the same price as the full program just to update an trouble-free program.

Other than the space used up, I don't see what harm there is in installing it on your laptop. S&T does a fairly shallow install compared to most other applications. Whatever is causing the crashes on your desktop will not necessarily recur on your laptop.

P.S. If you get a "Send error to Microsoft" dialog after the crash, you should send in the error report. The more people that send in a given error, the more likely it is to get fixed in the next version.

i was wondering if there were some pc based software that would compare one file to another and show the differences between the two - that would allow one to copy a 2007 file and submit it to 2009 software and let it "convert or upgrade" (or whatever it does to the file) - then compare the two files to see what the software did to the 2007 version of the file - hopefully it would be something simple like a filename change - OR - maybe i've had one too many glasses of wine this evening !!!
