I have been using this version (IS Pro 5) for sometime (never felt the need to update to "latest & greatest, when what I have works), when clicking around your site, I found “custom sound packs”. But, looking thru the settings in sounds, I can not find away to install the sound packs. Am I missing something?
Not sure, if you use IS or Pro, but you should update to version 7 anyway.
Yes the last version of AIS 5 was released in January 2011 so it is almost two years out of date.
In security two years is a very long time.
