Project not re-calculating ???

[akm]

When open msp2007 file get error message below...

"No calculations can be performed now.
There is a circular relationship in task 295.
The successors of this task refer back to this task or its predecessors,
causing a circular reference.
To remove the link that is causing the circular reference, select the two
tasks that are causing the circular link, and then click Unlink Tasks on the
Standard toolbar."

When go to the task (295, last task of project) there are no links and if
delete the task, the error message appears (when open project) again with
reference to another task that has no links.

Project is also (assume because of above) not re-calculating when change
dates at tasks (have options set to automatic re-calc).

Ideas ?

Thank you for your help.

Do you wish to debug?

And then the 'help' page comes up.
Maybe related problem ?
Thanks again.

akm,
Circular relationships are always "fun" to ferret out and fix. The first
thing I'd look at is a link on a summary line. There should be no links
to or from summary lines. If there are, reconfigure them to only link
between performance tasks.

If you do not have any links on summary lines and/or you eliminated them
and you still have a circular relationship, try the following. First
turn auto-calculation manual, if it's not already on manual. Then sort
by start date. Look at the Successor field of each task in the sorted
sequence. If any tasks have a Successor who's ID is less than the task
you're reviewing, there is a good possibility that task is part of a
circular relationship. In other words, all links should be of the
forward-pass type.

I have no idea about the second error. It sounds like the file may have
an Open event macro that is stalling due to an error, or possibly
Project has corruption in it's help file. You could try Detect and
Repair under the Help menu.

Hope this helps.
