problem after tables import

[leMich]

hi,

i just installed version 0.13 on my local server. All worked fine. I tried then to import the tables contents of my old 0.10 site. The importation is ok, but the site and admin are down now : Fatal error: Cannot redeclare class cssmenu in c:\.... If i delete this module, the bug appears in an another module, etc.

what is the problem ?
