After update, no access to "settings"

Hi together,

we are working with PIWIK since several months on 7 websides. Until last update everything fine, but after the update on 0.4.3, we have a problem. The statitistics are fine, but it is impossible to get the “settings”. We received following message: The plugin filename ‘EX3AC0~1/EX3AC0~1.php’ is not a valid filename.
Even after a complete new installation, the same issue.
Can anyone help us?
Many thanks in advance.

Looks like you extracted the files with an older version of unzip or windows that did not support long file names.

Remove the files with mangled filenames and re-install.
