Hi, Rodrigo, if I do a look on your file with an simple editor (Windows), then it looks very other as all my own th2-files. In you file is written all in 3 lines. And I think that is the problem in generally. Your file is not really readable for Therion. I`am using Therion 5.4.1 on Windows 7 prof. This file looks like it is coming from Topodroid without compiling it to therion-format, if I`am right. Regards Markus My th2-Files looks like this (a part of a file: encoding utf-8 ##XTHERION## xth_me_area_adjust -138.0 -138.0 1545.322834645669 1838.0 ##XTHERION## xth_me_area_zoom_to 40 ##XTHERION## xth_me_image_insert {234.64566929133855 1 1.0} {174.8031496062992 1.0} Farrenwiesschacht-alles_p.xvi 0 {} ##XTHERION## xth_me_image_insert {349.60629921259834 1 1.0} {1701.2913385826766 1.0} Farrenwiesschacht-alles_e.xvi 0 {} scrap scrap1 -projection plan -scale [-128.0 -128.0 1545.322834645669 -128.0 0.0 0.0 42.50239999999999 0.0 m] line gradient 137.0 82.0 203.0 89.0 323.0 243.0 323.0 243.0 smooth off endline line gradient 108.0 125.0 179.0 121.0 308.0 244.0 308.0 244.0 smooth off endline line gradient 91.0 166.0 161.0 155.0 308.0 259.0 308.0 259.0 smooth off endline line gradient 85.0 213.0 147.0 216.0 275.0 251.0 275.0 251.0 smooth off endline . . . . . endscrap Von: Therion [mailto:therion-bounces@speleo.sk] Im Auftrag von Rodrigo Severo via Therion Gesendet: Donnerstag, 22.

One of the sketches got way bigger than it should and is presenting errors like: can't read "xth(me,cmds,5,18,x)": no such element in array I already reduced the file to something really small and I still get these errors most of the times I try to open it. Any ideas on what could be the cause? I send attached both a small version of the sketch that presents the error and the complete log of the error. Regards, Rodrigo
