Tracks Stop For 1 Second Playing Back

[Emilio Guifarro]

I moved Hoster 5.1 from a desktop to a laptop and I did all the updates to it.
I just noticed that after some 15 to 25 seconds into playback, sometimes songs stop like 1 or maybe 2 seconds then it resumes playback but the lyrics desynchronize with the music. It does not happens with windows media player or any other player, just with Hoster.
I never had this kind of problem or heard about it before.
I already uninstalled Hoster, re-did the windows ajustments and re-installed Hoster but no solution.
if I replay, sometimes it does not stop
HP WORK STATION, I7 2.7 GHZ, HD250 GB, NVIDIA QUADRO 3000M WITH 2GB DEDICATED, WINDOWS 7 PRO 64 BIT, RAM 8 GB

Any idea of what this might be?
