Cubase 5 crashes when using Cubase Plug-in Set.vst3

After update to 5.5.1 and then to 5.5.2 I suffer very strange sudden crashes of Cubase. Mostly it happens during loading a project (it’s quite big, about 30 VST instruments) but recently I see crashes during work.

I discovered that the crash is related to Cubase Plug-in Set.vst3 file in vst3 folder. Here’s the crash dump I see in log (it’s the same for every crash):

Cubase5.exe Version 5.5.2 Build 637 - 30.1.2011 1:42

Timestamp is 4c93c509 (Fri Sep 17 23:44:09 2010)
C:\Program Files\Steinberg\Cubase 5\Cubase5.exe

Exception code: C0000005 ACCESS_VIOLATION
Fault address: 2583E817 01:0012D817 C:\Program Files\Steinberg\Cubase 5\VST3\Cubase Plug-in Set.vst3Bytes at CS:EIP:

I use 64-bit version under Windows 7 64-bit.

When I move Cubase Plug-in Set.vst3 out of vst3 folder somewhere everything is OK. But I use many plugins from it and it’s a problem not to use the set.

Can anyone help me with this problem? Maybe someone faced the same crash and know how to fix it. Any info is greatly appreciated.
