HALion and HALion Sonic updates released

Hi I am getting missing sample errors since the update with many sounds, ie: Brass Section XXL patch in Halion 4.5.4.
I am Using Cubase 7.03 64 bit, Windows 7 Ultimate and my elc version is 6.5.4.1120.

Please help, i have a paying studio client next to me watching me trowel forums for answers, highly embarrassing.
This has only started happening today. Do i need any Halion Sonic updates? I never use Halion Sonic, just Halion 4 if that helps.

Rexx.
