Problems with installation

I have a problems with installation of +Gallery module on Drupal 7.23
The library was located in sites/all/libraries and it was the folder named "pluslibrary" from SeppeMagiels github (v0.9.2, last commit was 57d366dcf6 about \0020 sign)
I cleaned the cache and ran cron, so the library was visible (it was not even visible when I followed the instructions at plus_gallery.info:21[sites/all/plusgallery])
And after all I got system message like "Unknown +Gallery library version. please download bla bla bla"
I tried to use non-dev version with the same luck. I tried to use library version from jermartin77(v0.8.5) and it was all the same (though, at one of the configurations there was a massage "library is too old", but I don't remember exactly what was the module and lib)

I even tried to avoid version-acquiring-system at plus_gallery.module:19:23, defining $libraries['version'] as a constant string (I know it was stupid and the module with such a correction silently doesn't started)

For now I use Media Gallery module, but I'm not fully satisfied with it. It would be great if your module will work until mid september.

Thanks for your work! I hope the problem is not global.
