Random noise with new version(SOLVED)

[RaveP]

Hi, I installed the newest update and now I get some noise like "pffft" high frequenzes only ...like some lite versions of vst plugins have.
But I don't have any of these and it also appears in old projects and has never happend before in the older version of cakewalk.
If I play sound it stops it and just noise for about 2 seconds... But also appears without playing anything.
Cakewalk turns useless with this problem ?

 

Ps: You can also answer in german if you like

This sounds like a plugin that isn't authorised. IK Multimedia plugins typically do this.
