Recently active topics in Wuala tagged with permission

Hi, have windows vista with Kaspersky anti-virus. When right clicking a folder and sending it to the W: drive (Wuala), I receive a message saying I need permission. I can not find anywhere how to give permission.
Any ideas?
Thanks, Willemijn

would it be possible to set read, write, delete permission also for folders? like in windwos filesystem?

I have a Mac used by two users. If the first user opens a Wuala account, the second one cannot anymore: this happens because all files under /User/Shared/WualaSharedData belong to the first user and will not have write permission for the second user.

In particular, when the second user starts Wuala, a Java exception is raised:
...
Caused by: quickbase.exception.BasicFileOperationDatabaseException: java.io.FileNotFoundException: /Users/Shared/WualaSharedData/Data/Meta/MetaB.lock (Permission denied)
at quickbase.internal.files.Lock.<init>(Lock.java:34)
...

Can this be fixed? Is there a quickfix? Thanks,
