W580 Pocket Trainer problem HELP

I have a problem with the pocket trainer application, when I enter an Error message appears: "Failed to find valid data on memory stick or memory stick missing. No new data added."
The step counter and fitness application work ok, in Fitness\Results I have the data from the past sessions and in Fitness\Walking is the average of steps, but somehow the pocket trainer cant get this data.
In the file manager i can see a file named sportsstats.csv in the directory Memory Stick\Sports, it can be opened with MS Excel and has my training data. So why cant the pocket trainer read it???
Thanks

mine has also stopped working

Has anyone experienced and/or solved this problem?
Mine also stopped working, after I upgraded to R8BE with SEUS.
I tried everything: I formatted the card again, used a different card, reflashed the phone from scratch with Davinci, but the two Java apps (pocket trainer and walk around the world) still say that the stats file is missing or corrupted.
My only hope is to revert to version R8BA, but I don't know if it's possible to go back from CID53 to CID52.
Has anyone any kind of info about this problem?

I did a bit of research online and a bit of trials myself and I think I understood the problem, but I cannot solve it.

For some reason (maybe related to software localization), the release R8BE001 of the firmware changes the sporsstat.csv file in an incorrect format, i.e. it uses semicolons to separate elements and commas as decimal point, whereas the previous firmware used commas to separate elements and points as decimal point. The two Java applications (Pocket Trainer and Walk Around the World) cannot read the file anymore.

For example, this is the sportstat file newly created after a settings reset in the Fitness menu and after a brief training session:

[Sony Ericsson Training Data Export Format Version 1.0]
DateFormat,TimeFormat,DistanceUnit,EnergyUnit,Spee dUnit,OldestDate
YYYY-MM-DD,HH:mm:ss,Km,Cal,KPH,2008-09-05

0,2008-09-05,,AD,,,78,0.06,0.00,,,
,,,AC,,,78,0.06,,,,

This file works and can be read by the two applications. The file is updated by the firmware every 10 minutes and every time the day changes and the number of steps is updated. Everything works.

When you turn off and on the phone, the file is rewritten and this time it looks like this:

[Sony Ericsson Training Data Export Format Version 1,0]
DateFormat;TimeFormat;DistanceUnit;EnergyUnit;Spee dUnit;OldestDate
YYYY-MM-DD;HH:mm:ss;Km;Cal;KPH;2008-09-05

1;2008-09-06;;AD;;;97;0,08;0,00;;;
;;;AC;;;455;0,38;;;;

As you can see, semicolons are used instead of colons and numbers are stored as "7,54" instead of "7.54". This file cannot be read anymore by the two Java apps.

If I'm not wrong, this happened when I updated the firmware to R8BE001, while until R8BA024 everything was working (though I can't remember 100% when it stopped working). Since AFAIK it's not possible to come back to CID52 from CID53, the only solution would probably be to install a R8BA024_RED53 firmware, but I did not find it nor in this site nor in davinci or wotan...
