Webi Can't find infoObject

Hi,

I've got 2 .unx universes created from IDT. When I try to create a new webi report from either universe I am able to open up the report and see the fields. When others try to create webi reports from them, universe A works fine but when selecting universe B the following error appears:

"can't find infoObject of cuid AUhQWb8_G2VBpOSTHEtGvdo"

I've found that this cuid is to do with the connection used in the universe but I'm not sure why and how to fix it. This is the only connection on the universe and seeing as how I can create a webi report but others can't has stumped me.

I'm using:

BI 4.1 SP4 Patch 4 and IDT 4.1

Any ideas what the problem might be?

Thanks

Stuart
