For Serio Release 5 users, we've issued an updated Service Pack.
The main change is some improvements to SerioClient Express - it's now much faster in almost all aspects of operation. We've also addressed bugs and other things that have come up in Release 5.
To download the latest pack, simply log into the Serio support website (www.serio-support.com) and follow the links on the welcome page. Installation is pretty easy - just update the files that need updating (instructions are available in the Service Pack).
