Please help in recording 96khz with guitar amp sims

I want to record an electric guitar directly and when I switch the sample rate to 96khz the guitar amp sims lose almost all their gain and their low/high frequencies resulting in a very bad sound.When I switch to 44khz I odn’t have any problems at all.Is there anyway to play through the guitar sims with the higher 96khz quality or all those amp sims work that way so that you can’t play at 96 khz?I have Windows 7 and it happens even at the stnadalone amp sims.MR816 owner.Any help would be greatly apriciated.It happens to almost all of them (Lepou,Lecto,Legion,Amplitube,Guitar Rig)
