Panel problems with Capt Sim C-130 & 752

Had to install a new C drive, most everything saved. I also had to re-download CS's C-130J, AC-130 expansion packs and 757-200 Block A.Problem: On running, I encounter a black screen with the gauges at the top. Replacing the panels causes landing gear, props (where applicable), etc to disappear. Sometime back, I'd managed to replace the panels, but it required some tinkering and the like. I've forgotten how I did it, so if anyone can help me, I'd appreciate it. I'd successfully used Simshed's panel in the -130s and I want to do it again.Advice is requested; the opinions I've read a hundred times already.Thanks in advanceBob
