Thank you,
Nevertheless, I have imported the file into aMule. It seems that the debugged version is more stable than the ordinary version(due to lacks of optimizations?) because it dosn't crash each time I tried to import the file. It is a little weird. After 3 times effort, I manged to import it without crash! but aMule had shown the size of available parts zero, but after restarting the aMule It found the downloaded parts completely.
