737NG FMC/SID/STAR problems

[Guest jawbreaker]

hii'm quite confused, after trying to perform a complete flight for 10 hours now, i still run from problem to problem. haven't been flying yet, and slowly losing patience. here's my latest problem:i installed the SID/STAR package from your website and programmed the FMC for a flight from EDDK to EDDH. first, the SID/STAR database is quite strange (at least for german airports): when i select (for example) rwy 32, and an appropiate SID, it seems that they don't "fit" together. the ND is showing a route for the opposite direction. also the second waypoint is discribed as around 3000 miles away although it is visually shown right "in line" of the route. this causes a "insufficient fuel" message. attempts to delete that waypoint leads to a total mess. also as i try to switch through the available SIDs, to select a "better" one, the FMC messes up everything. sudden blackout screen (on the "RTE" and "LEGS" page), unexplained waypoints appear and disappear, and unusual signs are displayed (like squares, dots, hearts etc...) where letters should be. so SID/STAR handling is really hard. dunno why.i'm pretty experianced, i flew the 767PIC, DF737 and PSSA320 A LOT!!! i know FMCs and never had such problems. can anyone help me out?thanks in advantage, and excuse my long post and bad english...greets, stu
