how to manage two IDs

[moon]

Hi,
When I get to know Collanos I started a test with specific login data (I mean not those i'm used to have). After being satisfied by the functionalities I started a new "session" with an official ID etc... At this stage all is Ok and I've been using Collanos for some time (like 2 months).
two days ago I had to make a major change in my system and thus did a backup of the files in my directory i.e /home/moon/CollanosWorplace & /home/moon/lib (just in case cause the changes were only on the OS)
The problem started when I wanted to run collanos after these changes. it started like if I've never been a user and asked for login data (that I forget of course!). I asked then the support to provide me with my data and a new password, which was done quickly.
I got in return  two logins (in fact I had those related to my early tests and the second that I use). Unfortunately (probably cause of Murphy) I used the wrong login data to connect.... So no trace of my Worlplaces  and since then no way to get  back to my settings.
My silly question is "how to get rid of this account", or "how to connect under a different ID", or any how-to get back to my "sweet and comfortable settings".
Any help will be much appreciated.

ps: I'm not sure my case is similar to the one posted by : ben@ic3
