Version 9.0.23.32 having issues with file shares -Recommend not updating

We have found after some deployments of the newest version that a percentage of clients are having issues with files on Windows file shares.  With some clients, Excel spreadsheets are showing as blank upon opening.  In our case, every time Webroot is closed, the file share issues go away.
 
We have an open case with Webroot.  They have told us this issue was discovered and known (as of this time, it is still not posted on the forum's "Known Issues"), but we received conflicting reports;  some techs knew the issue, but other people higher up at that point did not.  This pointed to us for a real need for communication within Webroot, as it seems like the left hand may not know what the right hand is doing.
 
At this time, I would actively discourage any MSP or large business client from updating past 9.0.21.18.  In fact, my topic is also a request:  I need the MSI file from 9.0.21.18 so we may roll back our clients, and more importantly, I need to find out how I can download specific versions of the installer MSI at any given time I need them, so if we experience an issue, we may roll back.  This would prevent opening a support ticket if I had direct access to multiple recent versions of the client.
