Don't know if this will help...

Yesterday (Dec 9th) I got the "xml error - junk after line 2" thingy.
I have updated nothing in the last 6 months (can't afford it) and have never had this problem before.
On loading P6 this morning I got the same error.
Both times this happened after Poser had been running for approx 1 min.

This morning I happened to glance at my firewall and realised I was still connected to the net. Usually I disconnect the cable when I'm not actively using the net. Last night I must have forgotten to do that.

I read this thread and thought "Umm...."

So I disconnected, loaded P6, loaded a character, twiddled my thumbs for a couple of minutes (well, glugged some beer, actually), and... nothing happened

So I checked my preferences and lo! and behold! - "Check for Updates" was checked. (I didn't even know it was there!)
So I unchecked it. Closed Poser, re-connected, checked back into Rosity and re-entered this thread. And started posting.
Just to double-check, I restarted Poser and did the little mini-tut pic seen above: "Don't you make my blue eyes brown?" No error mesage:-))

So I guess that the "Junk after line 2" has got to be something to do with checking for updates....
(PS - The pic is pure frippery - I just wanted something to do while waiting for the error message to show up - or not... And BTW, who was it who sang "Don't you make my brown eyes blue?")

Cheers,
