Xen users - Mar 2010 - win7 x64 gplpv_Vista2008x64_0.11.0.210_debug.msi to gplpv_Vista2008x64_0.11.0.213.msi

Hy James,
if I try to update from the running
gplpv_Vista2008x64_0.11.0.210_debug.msi to
gplpv_Vista2008x64_0.11.0.213.msi I get a blue screen and the machine
fails to boot afterwards, system restore works.
What is the intended way to do this?

Florian
