CSV to GPX conversion

[RayL]

I've just returned from a long trip having used Columbus V990 to track where I've been. I want to convert all the files to gpx. Routeconverter worked perfectly for almost all of the csv files - thanks!. However for 2 files it could not recognise the type of file. I've looked through the forum and found no help there. I've examined the files and to my unexpert eyes they seem to be of the same form as those successfully converted and they are smaller than some converted files. I've attached zipped copies of the difficult csv files. Any help would be appreciated.
Thanks
Ray
