Now, my question is - if I recall a job and its images, and then change the profile will it still print the same crappy way, or will it accept the new profile.
Yes it is "accepted", what ever profile is set shows in the Job Properties, right there on the main screen, not hidden in any way.
You could check the basics again:
DWMP_ PK is the correct profile from the Epson web site.
Double Weight Matte paper is definitely set in the driver along with No Colour Adjustment.
There are no nozzle blockages.
Have you used this paper & profile before with B&W and colour, were the results ok.?
Tip for the future: Save Printer Set-up's for paper/printer combinations so that the correct profile and driver settings can be re-called in one step; no forgetting to set the correct profile then.
I'm sure there are no issued related to Q-SE 2009 v268 but why don't you upgrade to the latest 2010 v209?
