I was wrong. I was thinking that I had version 8.xxx, but I had 9.2.2. My OS is CentOs 5. I found the error log file and I think the problem was this:
http://kb.odin.com/8338
In the link it says that: "The problem has been fixed since version 9.5.0.", so I updated to this version. Unfortunately, the server still doesn't start and I see the same error:
2011-08-08 15:51:24: (log.c.75) server started
2011-08-08 15:51:24: (network.c.336) SSL: error:00000000:lib(0):func(0):reason(0)

I also received this email:

I tried running 'genkey', generating a new key but plesk still doesn't start. What else could I do?
