Save file not available on my main account

[bronsonfu]

So last night I booted up ttw on my secondary steam account without realizing. My saves were available so I just played ttw on that account until I realized I was on the wrong account. I just switched back to my main account but I cannot access my newer save files that were created while playing on my secondary account even though I have access to the save files on my computer. What can I do do regain access to the save file through my main steam account?
