If you signed into your iTunes Store account and enabled iTunes Match in the other User Account then I'm afraid you're stuck for the remaining days. The TOS of iTunes Match doesn't allow sharing across User Accounts on the same computer.

I checked and I didn't enable iTunes Match on the other computer.
I sent an email to Apple's iTunes team and I got a reply that this was a known issue and they are working on it. Pretty frustrating. I have not had such good luck with iTunes Match.
