As for the 'bigger problem':
you ought re-install the desk software. You may obtain it here:
http://www.avolitesdownload.com/Downloads/Pearl2008.stm (registration is automatically: you'll get the download link within seconds even today). The prlavos.dat comes with the software, along with installation instructions.
However, it's strange the desk 'forgot' that file. weak battery? corrupted memory? loose cables/connectors?
As for the personality file:
- go to the personality download page:
http://www.avolitesdownload.com/Persona ... efault.asp
- as Nic indicated, the fixture is known as 'Led Par 18x3Watt RGB 7 DMX'. Thus,you might wish to search for
-- desk type: Pearl2008/2010/Tiger
-- Manufacturer: Showtec
-- Search-String, e.g.: 18x3
The file is called SHLP183W.R20, is on disk #21 (and in the cache), will show up as SHLP183W on the desk...
Happy new year!
