Just Updated to TC 10.40 -- Can No Longer Open Manual Tests

Is this a known issue? When I launch my suite, I'm warned "Cannot load data for Manual Tests. Make sure the appropriate plug-in is installed" and some manual tests I had archived earlier won't open. The tooltip for the now unavailable Manual tests reads "The project node is not available. The factory is not installed." I tried to check for plug-ins, but I can't find anything about adding or re-enabling manual testing. I looked for tcManualTest.pls and tcManualTestEditor.pls in  C:\TestComplete\Bin, but those files are not there.



Has anyone been running into this same issue or have any suggestions?
