Reset the Admin Activity Log error

[JC.M]

I'm using ZC v.1.3.8sp1.

I just transferred my site to another hosting. When I login into admin, it highlights at the top

WARNING: The Admin Activity Log table has records over 2 months old and should be cleaned

Whenever I click on the RESET button it gives me this error:

Warning: require(includes/classes/currencies.php) [function.require]: failed to open stream: No such file or directory in /home/local/public_html/sitedir/admin/store_manager.php on line 12

Warning: require(includes/classes/currencies.php) [function.require]: failed to open stream: No such file or directory in /home/local/public_html/sitedir/admin/store_manager.php on line 12

Fatal error: require() [function.require]: Failed opening required 'includes/classes/currencies.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/local/public_html/sitedir/admin/store_manager.php on line 12

I can't figure out what caused this error and how to fix it. Any idea?

Check that the files at /admin/includes/classes/currencies.php
Is there and not "0" bytes to start
