Preceding-sibling doesn't work anymore for me

Hi,
I installed windows 7 on my machine - so I upgraded to Firefox 3.6.3.

I had to upgrade Selenium IDE to version 1.0.6*.
I have a simple
//tr/td/div/span[contains(text(),'TEXT')]/preceding-sibling::td[2]/a and
when I use
Selenium it doesn't find the locator?
When I only type //tr/td/div/span[contains(text(),'TEXT')] the locator
is found.
When I add preceding-sibling, or following-sibling it doesn't work correctly.
I get
the error message: error = Error: Element
//tr/td/div/span[contains(text(),'testuser')]/preceding-sibling::td not
found.
In the previous version of SELENIUM IDE this worked fine.
Can anyone help me pls? Maybe I only forgot to add something or to configure something?
My test are full of preceding-siblings

thanX

ok - my fault:

it has to be:
//tr[td[div[span[contains(text(),'TEXT')]]]]/preceding-sibling::td[2]/a

sorry!
