wceload cab file install on storage card -> data abort (sdmmc.dll)

[jwei]

i have a simple cab containig a HelloWorld.exe (appliaction path is 'storage
card')
this cab gets installed fine on windows ce 5 (cf 3.5) using wceload tool
(pinvoke) : wceload return code is 0 and the file HelloWorld.exe is on the
right place (storage card)

now i try to add am extra folder 'xxx' and a text file (about 1kb) to my cab
project, so the structure of the cab is as follow:
/HelloWorld.exe
/xxx/dummy.txt

now i get an return code of 1 from wceload tool and a 'data abort ..
sdmmc.dll ..' on the console during cab installation - but the extraced files
are on the right place ... ?

what about this data abort ?
