Hi Lynn
Slowness is not due to older versions of Adagio.
Slowness is most often due to your anti-virus software being improperly configured. It needs to exclude the \Softrak folder both on the server and the workstations. One way to test this is to uninstall (not disable, uninstall) your anti-virus software temporarily and see if it is the culprit.
If not, then ask your consultant for advice. This is beyond the scope of the Adagio forum.
Check what version of a module you are currently using. If it is the same version you want to install but an older date (YYMMDD), then install the service pack. If it is an older version, then install the upgrade. It's one or the other - you won't need both.
