have similar problem not installing all definition but maybe just half of it... try install one-by-one starting from youtube - not working too

but first half is OK. may be something in XML-file?
I don't know may be it was posted here but is it any way it can parce this links

Becouse for now if there is something before v=XXX it's not parsing
and finally I have problem with youtube and vbadvanced:
and it's braking all other modules in vbadvanced after that.
