AutoCAD here reports missing shape fonts, specifically one called LV_TOPO_2012. Your 2010 file is also saved down to 2004, pre-2007 when fonts and things changed somewhat.
Also, why are you trying to oh-so-delicately rig MTEXT over a grided linework (aka a TABLE) instead of using TABLE command to do what appears to be, well, a table with text and entries? Curious method, good back in the DOS days of AutoCAD but unusual to see these days.
I set your MTEXT spacing to 350 (not 333.33335 that you had) and made a copy adjacent and changed it to 550. Closed the file, closed AutoCAD, opened the file, no settings changed. I did NOT save down to 2004.
