When I try to compile I get this error:ERROR: Unable to write to output file D:Flight Simulator 9SceneryWorldSenerytraffic_TEMPAny ideas?

Did you mean to type "Scenery" or does it really say Senery? If so, then you need to find the correct folder.If the error message really says "Scenery", then it appears that your World/Scenery folder is somehow locked or write protected. Try fixing this in Windows Explorer (right click the folder and choose Properties).If you don't see a problem, change the Destination folder for the compile and try again. Then move the file from there into the original folder.Hope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___

Ya, that was my typo. I'll try it again after I reinstall UT. I had a problem getting the latest update working. I'll try you're suggestion on selecting a different folder.Thank,
