What version of the Blender Source Tools are you using, and can you link to the exact SMD file in question?

There is probably an invalid character in a bone name slide your SMD file. Try editing the file in a text editor and changing any bones with unusual names. It will probably be obvious where the problem is.

guys latest source tool seems like is not supported by blender 2.81.
sorry for all the inconvenience

to be honest I'm a noob in these things. So there's no way I can edit the files in text editor. Though I worked with SMD before and opened them in blender but never encountered such error. In fact I was able to open those two files(attached in my previous comment) once before. It worked perfectly that time
