Good morning,I write here as I have a problem with diverting PMDG 737 using FMC.I fly B738 form EPSC to EKRN to practice diverting to alternate airport (in this example origin airport- EPSC).Route for this flight: EPSC DCT GOMEX L996 GOSOT DCT EKRN. I plan to land on RWY11 using ILS, later I execute G/A and adhere to hold over FAU (Inb CRS 291, Left turns, 1 min, ALT 2000) as published.Now I decide to divert back to EPSC, so I select RTE Page, and then I change DEST from EKRN to EPSC. Everything is ok...I begin to insert first waypoint of my alternate route to EPSC which is: GOSOT L996 TILAV UL87 XELOL UZ491 DEMUR Z491 BEDAMI push LSK 8R, and...I have RTE DISCO which is still normal, but here waypoints are changing order and this is now unusual situation. All attempts to liquidate discontinuities fail. I needed to insert each waypoint on the LEGS Page (this is not appropriate technique), then I've passed to Perf Init and I've inserted new CRZ ALT FL130 (it was lower than TRIP ALT) confirmed by pushing EXEC, but I was unable to restore SPD/ALT predictions on the LEGS PAGE, FUEL Predictions na PROG Page, so VNAV wasn't workinkg.Second problem is running away stabilizer trim. When I operate it in the air or on the ground (A/P is not engaged) it escapes opposite direction. For example: I want to set trim for take off from 3 to 6 degrees I push the button and wait until I'm on 6 degrees then leave, but trim is going back to 4-5 degrees. To solve this I need to set 8-9 degrees then allow it to back to 6 degrees.I have got Windows Vista x86 (32 bit), FS9(2004), PMDG Stary B736-7 v. 1.3, B738-9 v. 1.1;Every help will be very appreciatedThanks anyway.
