We are investigating an issue with SPSS in the Commons that is effecting the Windows machines. The Macs and the laptops are still working fine, so steer patrons that way in the meantime. We will update as we get some answers.
EDIT: This seems to be effecting only one computer (2029). We tested several other machines throughout the commons and SPSS was working normally. We repaired the install on this machine and it seems to be working fine now.
