Plugin installation errors

I keep getting this error when installing some of the necessary plugins:

object(WP_Error)#1064 (2) { [“errors”]=> array(1) { [“plugins_api_failed”]=> array(1) { [0]=> string(219) “An unexpected error occurred. Something may be wrong with www.ads-software.com or this server’s configuration. If you continue to have problems, please try the support forums.” } } [“error_data”]=> array(1) { [“plugins_api_failed”]=> string(2) “N;” } }

Please advise,

Phillip
