Connection between HUD in SL and pc program no longer working (worked a few months ago)

Hi Thomas! I'm still using your incredibly useful Full-SIM Object Scanner Pro 2.3.263. Sometime in the last few months it's stopped working, unable to contact between the PC based Universal Gadget Controller V1.18.348 and the Full-SIM Object Scanner Pro 2.3.263 HUD in SL. Did something important change. I hope all is well in your real life, you did some magical things here in SL. Thanks!
