You need to patch the hell up.Listen to me closely
http://download.ts2009.com/patch/42203_to_44088.exe <----Thats the patch download it
when its done CLOSE ALL PROGRAMS,DISABLE ANTI-VIRUS and INTERNET
RUN the patch and DO NOT OPEN ANY PROGRAMS or PRESS ANYTHING if u do the patch WILL be DISRUPTED and you will HAVE to REINSTALL Trainz ALL OVER AGAIN!
The patch will take at least 1 hr 30 minutes I patched straight from 42203 to 44088 and it took roughly almost exactly 2 hours.
