invalid optcode

Hi,

After updating to 3.0.4 i receive
this on the “add new job” page

Fatal error: Invalid opcode 153/1/8. in /hhh/hhhh/public_html/content/plugins/backwpup/sdk/WindowsAzure/WindowsAzure.php on line 26

I tried to uninstall and then install the plugin and remove all other plugins, no change.
