Graphics, Figures & Tables ⇒ error runtime "5" invalid routine or argument

[leoiacovone]

Hi! I have just installed the latest version of excel2latex and use Mac OS X (10.5.8) and Office 2011. Unfortunately when I try to use it I get an error message "Error runtime '5' " and below "Routine call or argument invalid".

Anybody could help? I have been trying to sort this out for more than 2 days now

Thanks in advance!
