The location of the texture file shouldn't make a difference. If Poser can't find the texture file it wants it'll complain about it but shouldn't tank like that. As to the update, when you run the update the Poser.exe and some other files get replaced. You'd just have to run the update .exe file and it'll ask where the version of Poser to be updated is located. At this point, it may be the best course to UNINSTALL Poser the re-install it. If you uninstall, just the Poser program stuff gets deleted and the folders containing any of your imported materials will remain intact. Re-installing will put Poser's stuff back out there and you can see if there's still a problem. Boy, something is really screwed up on this one. :(
