Update Valerie Ann sent me the file from her Version 5 and my version 2010 read and converted this file OK (in fact I checked the specification and 2010 will read and convert any version from Version 5 or later). But as Art says the converted version will not read back into Version 5. The situation about running older versions of FTM is as follows: Anything prior to version 2005 (do not confuse this with version 5, version 2005 is sometimes referred to as version 16) can not be run on Vista. Version 16/2005/2006 will run on Vista but you need a patch from FTM to make it work properly Version 2007 and later will run OK on Vista.

However, I think John Steele is correct. I, like John, every few years upgrade my version of FTM and my files are still readible. But, as John says, the newer version 2010, will probably read in the version 5.0a version you have, but it may convert the format so that it is no longer readible by your older program. I am running FTM 2005 on my desktop and laptop, both of which are XP based. I regularily move my FTM files between the computers by CD and am going to try doing it with a flash drive. I have had no problem. Additionally, I have FTM 2008 on my laptop and it read in a file created in FTM 2005. I have not done the reverse. I did not like the 2008 presentation so I have kept my data in FTM 2005. You could send a file to John, as he suggested, as a trial. I am sure it would work. One thing that you could also do is contact Genealogy.com and ask them your question. Additionally, I would imagine that if you do run into a problem with an upgrade or computer operating system versus FTM application conflict, they could resolve it for you or even convert your files for you.
