You're welcome.

It's nigh impossible to say why you are getting "congratulations,no threats found." now,but got 5 to 10 threats with 1.4,without seeing a log.But,there are a few possible legitimate reasons of why that might be.
If what was being found before were something like Firefox tracking cookies,version 1.4 sometimes had trouble removing Firefox tracking cookies,and the program would say they were removed,but they would be found again on the next scan,while the new Spybot does not have that problem.
Also,if you didn't have sdhelper enabled on the Spybot 1.4,but enabled it for the newer version,then it's possible Spybot's resident sdhelper is blocking IE tracking cookies now,whereas it wasn't before.
The same is true if you recently configured your browser(s) to block third-party cookies,then Spybot would not find as many tracking cookies.
Also,can you remember what colour some of the things Spybot was finding before were?If they were green,you may have been scanning for tracks before,but Spybot may now be set to a spyware scan only.
You also might want to be sure you actually are scanning for spyware.Spybot should do that by default,but if you want to be sure,you can open spybot,click mode,then advanced mode,settings,filesets,then be sure there are checks beside the Integrated search for spybots section.
You can return to default Spybot mode by clicking mode up top,then selecting default mode.
There's probably no reason to be too concerned,but if you're having any malware problems or computer problems,then please let me know.
