Mhs_mouth compression not found

[sam1_64]

Hello, my problem is that when I make lip sync on mhx model with papagayo moho .dat on blender, the animation is gone if I close blender and reopen the blend file, even the keyframes are still there in the timeline. If I then click for example reset visemes button I get this error;

Traceback (most recent call last):
File "C:\Program Files (x86)\Blender Foundation\Blender\2.65\scripts\addons\io

I have read the documentation on lip sync and can't figure out what I'm doing wrong

Should be fixed in r4855. You need to download an up-to-date Blender from graphicall.org (available tomorrow or so), or copy the mhx importer from MH svn to Blender addons directory.

Thank you Thomas, I'll try that graphicall blender when available, but meanwhile copying the mhx importer from MH svn didn't help and the problem persist.

Thank you, working now. I updated the MH svn and copied the mhx importer to blender, and didn't even need to upgrade blender

I am having the same problem in r4961
mhx_mouth compression cannot be found once the blender is closed and reopened. All mouth animation are ineffective.
Need help

It is not enough to updata MH, since the bugfix is on the Blender side. You need a fresh Blender from graphicall.org, or copy tools/blender26x/mhx_import/io_import_scene_mhx.py to Blender's addons directory.
