the module samples 2box problems

[drummologo]

hello guys sorry for my English, I have about 10 days to set 2box and wonderful and I must say, however, I noticed some strange things .... with "extreme sample converter" I did some vst samples in wav format with 16 layers, dsoundtool then I converted the wav format DSND and put into the form 2box, and here the problems begin .... while the sound samples you just created some times you hear strange noises kind of background noise very loud or strange sounds as hum, but I heard the sounds in preview and they were in place, this only happens with samples created by me, this thing happens even converting the samples with his editor 2box finally when I try to delete the samples are not cleared ... remain the champions but has 0 KB, or took the 2box used and the OS and 1.10 some advice, thanks.
