This is exactly what happened to one of my sites which inspired me blog the process in case the same thing happen again 😀 You must use sub domains.
Setting Up Multi Sites in WordPress – Part I – The Config File – you probably have already done this
Setting Up Multi Sites in WordPress – Part II – Wildcard Subdomains – this will be the most important one for you to follow – it may seem daunting but I managed it and wrote it as I did each step and it worked. Initially I needed about 3 other sites to help me figure this out which is why I blogged it to save time looking again if needed.
Setting Up Multi Sites in WordPress – Part III – Network Activation took me a while to figure out this step but once I got it working I blogged that too!
Hope this works for you – it did for me – Good Luck!

I want blogs on sub-directorys.
I am going to try this:
Find an old version of WordPress MU and install it to my root.
Export from old WordPress install and import into target WPMU install.
Then, I will upgrade to WP 3.0.
This should allow one to use sub-directories instead of sub-domains. I am in the same situation because godaddy hosting does not allow to use sub-domains. I’ll keep you all posted.
