If your Reader will autorun an SD card, the easy solution is to run Igorsk's Universal Flasher and wipe your current firmware. Run the Flasher, choosing option 7. Then, run the Sony Updater. You can get the Universal Flasher by clicking the link in my sig.
Otherwise uncompress the Sony Updater (it's really a big zip file) and change the file prs505/eBookUpdater/assets/updaterAssets/PRSVersion.dat so that 110018040 reads 110018041 - once that's done, the Sony Updater work at any time.
