Zoho Office Plugin

Zoho Office Plugin

I Installed Office 2007.
After this i install Zoho plugin.
I have two problems
In Excel 2007, the plugin does the log on OK, after this it show "Login to Zoho Sheet to view WorkBooks" and a OK button, i click in this button.
On Add-Ins tab i select Open, it shows my WorkBooks, but when i click in any Workbook it show "Error ocurred while Opening the Workbook".
In Word 2007,the plugin on the log on process shows "An error ocurred while configuring the local setup for the user.Please check System Space and acess permissions for the folder" and a OK button, i click in this button.
On Add-Ins tab i select Open, it shows my documents, but i click in any document and nothing happens.
I`m Using Windows XP Sp2,IE7, Office 2007 all in brazilian portuguese.
Can anybody solve this questions?
Thanks
Paulo
