You may want to work with our support team (support@alteryx.com) regarding this. It sounds like that dataset was either wasn't installed correctly or not installed at all. The "An unknown error occurred in PI_PushAllRecords. (Tool Id: 1)" error message is generated when a dataset isn't selected in the Allocate Input tool - so that's pretty in-line with your first error message.
It shouldn't be an issue that you have Q2 and the Server has Q3 - because you selected the "Most Recent Vintage" option. Alteryx will look for a vintage tag written into those datasets and select from there.
One thought - on your company server, was the data installed as a "Network Install"? If so - you may not have completed the installation process. Once the data is installed to the network - you need to navigate back to the location where you installed to the network, and run the datainstall.exe again. Select all of the data - then when you get to the "Location" tab of the install - you need to select "Register from a network location" and hit finish. This final step will point Alteryx to where the data resides. All users (including the server) that use the data will need to complete this step - if you had installed as a network installation.
