Log in to Sage 50 Accounts Script Error

Hi

Been trying to log in to my Sage 50 Accounts v28 since yesterday and keep getting an error which says

An error has occurred in the script on this page

Line: 0

Char: 0

Error: Script Error

Code: 0

URL 

Do you want to continue running scripts on this page?

Yes/no

I've tried saying yes and no and still nothing. I've been on help and cleared cache

Any ideas?

Thanks
