IXEG 737-300 Issues

[Gurinder]

I acquired IXEG 737-300 in November 2018. I use X Plane 11.30 on 2018 iMac with 8 GB VRAM and high end microprocessor. I am experiencing following issue:

FMC and/or PFD and/or ND lock up during flight and sometimes at start. Activating the debug mode sometimes causes these to start working again.

I have reinstalled X Plane 11 and IXEG737 again, but the issue has not gone away.

I am not experiencing this issue with Zimbabwe Mod 737, Flight Factor 767, or Tolis A319.

Is any one else experiencing these type of problems with IXEG?
