This stinks and we don't have a good sandbox workaround yet -- certainly not one that would pass App Store review yet. I can't make any promises that we'll be able to find a submittable workaround in a reasonable period of time, so:
Please contact the App Store support team and ask for a refund. You deserve a working app, and while I'm going to describe a workaround below it's not 'good enough' to keep QuickCursor available for sale. So I'm removing QC from sale in the App Store today.
So…
Here's what I've found with iA Writer under 10.8: The new 10.8 Open/New Document dialog box (with the iCloud/On My Mac options) is a major point of conflict. QC can't force Writer to create a new document from it or even dismiss it, and then the OS X sandbox seems to kick in (this is my guess) and quarantine QC for trying to open/work in another app's sandbox container. I'm not 100% sure that's what's going on, but it's the scenario I have so far.
The nasty part is that the sandbox seems to maintain the quarantine state until the next user session (it's apparently released after a log out/log in).
Here's what's working for me with iA Writer and other App Store sandboxed apps:
1. Launch the editor app first (iA Writer in this case). Having QC launch a sandboxed app will immediately quarantine QC, apparently.
2. Dismiss the "new document/open document" dialog if it pops up.
3. For iA Writer only, Byword doesn't seem to care: Open a new blank document (maybe you don't need to, Byword seems OK but Writer throws a fit sometimes and re-invokes the New/Open dialog box instead).
Like I said, that stinks and it's not good enough. I'm sorry for the very poor experience and please ask the App Store for a refund immediately. We're removing QC from sale in the Mac App Store effective today.

Greetings -- I just purchased QC and installed on my MacBook Air -- iA Writer is my editor -- NOTHING HAPPENS when I try to use QC. OS is 10.8.2 ... iA Writer is v 1.4. Am I missing something? Thanks!
