Cannot render sRGB JPG (avi) with the Text node


Please, could someone help me? I can’t render JPGs or AVI (in fact anything except EXR) with the Text node plugged in. Everything works OK until I connect the Text node. After that, the rendering process fails with “The specified transform file ‘D:\Aplikace\Natron\Resources\OpenColorIO-Configs\blender\luts\srgb_inv.spi1d’ could not be loaded. Invalid ‘From’ Tag”
Then I can only render linear/Linear with strange colors. I use the latest Natron Windows portable. Thank you in advance for your help.
