Hmm, well ACT 10 is supported on Vista, i would maybe suggest updating to the latest patch (10.0.3), but to be honest SMS integration is not something I've ever dealt with. You may be better off contact the people who make it, all i can see on the web page is this


"SMS4ACT is owned and distributed by 4Productions Ltd, for further information please call 08707 606140, email info@4productions.co.uk or request an information pack by land mail to 1-3 Lime Hill Road, Tunbridge Wells, Kent, TN1 1LJ"

I'd probably suggest giving them a call see if they have any troubleshooting procedures for the software.
