*Sigh* we were trying to get away from the "Got a problem? Reinstall" style answers. Is that really the impression our problems and workarounds page gives? Unhappy
The crash report text file should be called crash_report.txt
If you can't find it then you can get the error message before the DOS-like box closes by following these steps (assumes Windows):
(1) Open a windows CMD box / DOS-like box. Go to the start menu / the windows button at the bottom/left of the screen. There should be a box to type the name of the program you want to run. Type "cmd" and hit return. You should open up a DOS-like box.
(2) Change directory to the OpenRPG directory. Type eg, "cd c:/OpenRPG" or whatever the directory is called. The prompt should become "c:/OpenRPG>"
(3) Start OpenRPG. Type "start_client.py".
And then the error message should be displayed in the DOS-like box for you so you can tell us what it is. Note that you can go to the top left corner of the DOS-like box and select from that menu "Edit -> Select All" and then "Edit -> Copy" to copy all the text in so you can just paste it here. I don't know why they don't allow you to just hit Ctrl-C on the DOS-like box.
