Error: You do not have sufficient permissions to access this page.

Have you fix this ?

yes. it went away after i fixed the permissions on the files that need to be writable…

Which file o folder permissions you change? I can′t find which are the correct one ??

as per 4. in the installation instructions:
“Ensure the wp-content/themes directory and wpmp_transcoder/c cache directory are web-server-writable, as described above.”
thats all i did…
