error while loading contract manager atomic data: error loading the contract manager settings file: unable to read persisted json object from disk: open C:\Users\xxxxxxx\AppData\Roaming\Sia-UI\sia\host\contractmanager\contractmanager.json_temp: The system cannot find the file specified.

Scenario:

Downloaded and unzipped 1.2.2. Copied Host, Wallet and Renter to resources/app/Sia/. Took a while to run, and came back to Sia-UI closed (pc didn't reboot, as uptime wasn't interupted.) Reran Sia-UI, and was presented with the error above.

I have the same issue, although I may have taken a different path to get to the same result. I navigated to http://sia.tech/apps/#ui Next, I clicked on the SIA UI for users Windows 64 bit download link and then extracted the archive Sia-UI-v1.2.2-win32-x64.zip Next, I double-clicked on the file called SIA-UI.exe Soon, the Sia-UI had a message "Loading can take a while after upgrading to a new version. Check the release notes for more details." Later, I came back and Sia was now telling me: A critical error loading Sia has occured: Siad unexpectedly exited. Error log: Loading... (0/6) Loading siad... (1/6) Loading gateway... (2/6) Loading consensus... (3/6) Loading transaction pool... (4/6) Loading wallet... (5/6) Loading host... (6/6) Loading renter... Closing host... Closing wallet... Closing transaction pool... Closing consensus set... Closing gateway... invalid argument

I am running a Windows 10 OS. Steve
