problem unformatted texts with autocad file 2010

[00zylit]

Hello everyone, I have a problem with an old dwg I created a long time ago with a 2010 autocad version. now I needed to change it only that when I open it with autocad 2015 or even 2013 the writings are all distorted. being a technical relationship is full of writings so putting everything right would be a piece of work! Moreover if I try to install autocad 2010 on windows 8 from compatibility problems!
someone knows a command or a way to recover original formatting directly from autocad 2015 or with some free software!

thank you in advance!!! !

What do you mean by disfigurement?
font or layout problems? In the first case did you try to install the old font, use the big fonts, change fonts?
Is it a text or text?
cad free have been reported on the forum you tried them?
