Very little information which we could use to help you.
OS? DAW? Hardware?
What issues?
I have to admit I got very frustrated when I first tried to wrap my head around all the Virus TI features. And stumbled several times. Also ran into serious bugs. However, the sound is great, the hardware feels great, and after some fiddling the TI components started to behave. It's also a process to adapt and learn to live with the limitations. For some it works, for others not so. But I guess that was true for a Moog Modular as well.
