[Wine] runing a program

[pilar pazos]

I am an old user of Microsoft and a new user in Ubunto 8. with wine and 
I install some windows programs and add my licenses, test them and each 
one were running OK.
I off my computer and when I got back to it, I no longer have in 
wine-->programs  the list of my software.
Only notepad is shown.
I try to make double click on my  *.exe files, but no program runs.
How can I fix this.
Thanks for your help
