Problems wp super cache after upgrading to version 1.5.4 and 1.5.5

Hi, I have some problems with the wp super cache plugin, the problems started after upgrading to version 1.5.4, a few days later came the version 1.5.5 that in theory fixed the errors of the previous version, but it still gives me the same mistake

I get the following message:

WP Super Cache must be configured. Go to the administration page to activate and configure the plugin.

I configure and I get the following:

Error: The cache directory () did not exist and could not be created by the web server. Check the permissions.
I can not continue … solve the problems described and try again.

I reinstalled it and did the right test, everything works fine, but the next day or two days happens the same and the message, How can I solve it?
