Not sure if this is the most correct location for the question, but seemed logical as the problem is a plugin related issue.
I have Open Office 3.3.0 which has an SME plugin for saving files directly to the cloud (in my case GDOCS). I have configured SME with GDOCS as default cloud. When I go to save a file in OO the message comes back : Error 53, Line 52. No amount of filing around has been able to let me upload directly from OO to the cloud.
I am on a Mac Air with OSX 10.7.3 I have even tried to run the progamme in 32 bit mode and it is not helping to remove the error.
