Dear All,
We recently do a BW upgrade from BW 7.0 to BW 7.4.
Before upgrade,we use WAD 3.5 to design our BW report and then publish to our CRM protal.After we do the upgrade from BW7.0 to BW 7.4,we find that we can't connect our BW system any more using WAD 3.5,it give us an error:""Run-time error '91': Object variable or With block variable not set"".If we choose OK,the WAD3.5 windows closed, We can't design our report any more

Thanks in advance if any help.
