Modlos 1.5.0 database issues

Hello,

I am experiencing some odd behaviour with Modlos 1.5 and moodle database interaction.
My environment:
Ubuntu Server 10.10 64-bit
MySQL 5.1
Apache 2.2
PHP 5.3.3
Moodle 1.9.10+
Modlos 1.5.0

All of the above are fresh installs.
I installed Modlos via the regular block installation method for moodle.

The system is showing the following abnormalities:

Avatars list:

Status for all avatars lists as "Not Syncro DB". However, changes in in-world status (ie, offline, online) register correctly in the system.

Create Avatar:
When creating a new avatar, always get the following errors:

"User not found"
"It failed in making user of Modlos!'

However, Opensim avatar account is still created and can login to OpenSim normally.

Events

When trying to add a new Event it fails and the following message appears:

"You should have avatar ar least one"


I am sure this is related to the fact that modlos does not seem to be synchronising user information correctly at the database level.

All other server-side functions (ossearch, profiles, offline messaging, groups) are functioning correctly.

It would be great if you could give me some advice on what to try to rectify these issues.
Thankyou for providing such a wonderful management tool for OpenSim!

Rgds,
Adam
