Nero 5.0 help me PLEASE!

Well, i just installed Nero 5.0 and it didn’t work (when i click on file, program not loading). I tried to update aspi drivers from adaptec site - nothing… Then i tried to put wnaspi32.dll (143kb, v2.00(7)) to winnt/system32 dir - still nothing. Well, then tried to put latest wnaspi32.dll file (45kb, v4.60(1021)) to Nero dir - program loaded, but with errors like that: “The WIN-ASPI file ‘?.?’ can’t be found, therefore you can currently select only image recorders. Please check for correct Windows ASPI Manager installation of your SCSI-host adapter software. (Error 19: Bad Install!)”.
PLEASE look in your dir and answer what files are there (what size) or please describe what need i do (what files and where to put and when i need reboot my comp)!!!
P.s. many people like and use this program, but only i have this problem? strange… BTW, i got HP CD-Writer 8210e
