It's 100% repeatable and happens of my friend's system as well.
If I load Hollywood strings 1st Violins: 09 Legato Slur + Port Powerful System and start at the top of the list, by the time I get to the 6th sound
1st Violins Leg Slur Ni it will hang everytime and NOT load the sound in the server version.
However if I repeat this in the stand-alone version of VEP5, It works fine and I can load all the sounds.
It happens with the second violins as well. I needed to use these sounds.
As a work around, I used the stand-alone version of VEP5, loaded the sounds I needed and saved it as a channel set.
Then I loaded the channel frame into the server version of VEP5 and it worked.
If you have this library, can you check out this problem?
