Quicken Data Problems

I migrated a Quicken file from an old computer.  I was able to open it and use it without any problem, with the exception that it took a long time to load (there was an hourglass over the file for about three minutes).

I closed the file to do something else, but the next time I tried to open it, I was given a dialog giving me a choice of pointing to a new data file or using the one Quicken had "found".  I chose to look for a "new" file, when in actuality I was going to point to the old file.  When I clicked on the file, Quicken tried to convert the file for some reason (I'm using Quicken 2005 Deluxe on both computers).  It ended the process with a message that it couldn't convert the file (even though it "converted" it the first time I loaded it).  The message also said to contact their customer support, but I'd rather avoid that.

During this process, Quicken kept creating a folder called "Q01Files".  In that folder, there was suddenly another .qdf file by the same name as the original, but with a different byte-count.  It got hard to tell which was which, and both files were tagged as "corrupt" when I tried to load them into Quicken.

Beyond that, there are about 20 .qdf files on my old machine that Quicken seems to have created at whim.  I'd like to keep my machine cleaner this time around.

Anyway, thanks in advance for your help.
