ExcelBanter - issues while saving

Hello there...
|
| We have some issues with Office, mostly with Excel & Powerpoint, it
crashes
| sometimes in any file while Saving as..., 'Excel have an unexpected
error
and
| it must be closed', Recovery checkbox appears.
| After restarting the application it opens the recovered document but...
it
| cant be saved, same error.
|
| We install first Office 2003 SP2 and later we upgrade WinXP to SP2,
because
| after that we experience these issues.
|
| Any suggestion?...
|
| Thanks in advance, regards!
