+2126 No path through segment
The Viterbi segmentation failed to find a path through model with this data. Check that
data is not corrupt and that a valid path exists through the model.
What does "corrupt" mean? Can anybody help me? I need the results of that "corrupt" files....
Thanks in advance

I would suggest searching the HTK-users mailing list and if you can't find the answer then posting to that mailing list. I think I've seen this question asked and answered there (although I have to admit that a quick look in the archives didn't find it).
To answer your question, corrupt means that your data is not as you intended it to be. Byteswapping your audio is a common form of corruption. More specifically, your data should fit your models, else if all the observation liklihoods are extreme then no path will be found.
However, the most common cause of this error is not having enough observations for your HMM topology. Say you have a three state, left to right HMM and only two observations, then clearly there is no way to find a match.
I hope that fixes your problem, if not, there are many helpful people on HTK-users.
