Ade,
I expect your issue is creating an expression and giving it an alias "AS Mean" and then using the alias in following expressions. I never do this. Try replace the aliases with the original expression. For instance, replace every instance of Mean with ([Win1]+[Win2]+[Win3]+[Win4]+[Win5]+[Win6])/6. Do this will all alias usage. If you have to do this enough times, it might be good motivation to normalize the tables or maybe create some user-defined functions.

This worked perfectly in Access 2007.

Ade-
Please post the SQL from one of the queries that's failing.
The query engine / optimizer does change some between releases. I has to be able to "compile" your SQL in its buffer before it can execute it. It may have been close to the limit in 2007, but now won't fit in 2010, but there's no indication other than the Too Complex message.
There are things you can do to try to reduce the compile size - such as substitute short alias names.

Kindly assist. I have some queries which worked perfectly on an older computer. I get the message QUERY TOO COMPLEX when I tried running some of them on a newer computer.
Would you know how to resolve this ?
Thanks.
Ade.
