Error in List Module

[alife]

Hello!

First of all: I'm brandnew to isotope.
I have a page with the LIST module (isotope 1.3.8 stable).
When I want to show the page there appears an error. In the error log I can find this line:

[01-Oct-2012 15:25:46] PHP Fatal error: Uncaught exception 'Exception' with message 'Query error: Table 'slim_methodecomdb2.tl_iso_labels' doesn't exist (SELECT * FROM tl_iso_labels WHERE language='de')' thrown in /home/.sites/587/site2237/web/system/libraries/Database.php on line 686

Would be great if you could help me

best regards,
alife

Have you updated the DB in extension manager?
