Logic 8 crashes everytime I use it more than 10 minutes, please help

Question

Hi, I am new on this forum, so hi everyone.
I just bought these 3 items:
1) new mac Pro 8-core that it comes with Leopard 10.5
2) new Logic 8 pro studio
3) new digi 003 rack
I instaled the protools 7.3 software and the problems began! I got an error window saying that I had some missing extensions or somethin like that, later A safary window appeared saying to instal some interlock extensions, I did install it, after finishing the instalation I tryied to launch protools but the hardware was not found. I went to digidesign website and realized about the incompatibility between leopard and protools, so I uninstalled the protools software and desconected the digi 003 from my computer and uninstalled the interlock extensions.
ok so far...
After all this I decided to instal Logic 8 pro (I never used Logic before, alwyas work with protools) so I could start to familiarize with the program, but after working a little bit with it, Logic crashed, so I launched it again and the same thing happened to me. I had this problem about 6 times in two days!
So I verifyied disck permissions and I got a lot of errors going on; "Something in system/library/usertemplates etc...was unexpected and it should be whatever..." these kind of errors, about 30 in total. By the way, I have an small prohibbited icon over the "USERTEMPLATES" folder. after all this I click on repair disck permissions but nothing was repaired, every error showed again after running once more the verifying thing! so I launched logic praying to be able to work more than an hour but... logic crashed three times in a row in less than 1 hour work. So I decided to kill the people from the store! no, seriously, I reinstalled the Leopard on my computer with an erase and install from the original dvd. Notice that every time logic crashed I was doing something diferent, it crashed once while opening an instrument, other while doing time streching in factory, other just at the begining etc...
After instaling today again leopard and logic 8 with all the updates from apple/software update (mac os 10.5.2, logic 8.0.1) I still have the same problems;
-Logic crash very often whatever you are working on
-Disk permissions problems:
Verificando permisos de “INTERNO1”
Se ha encontrado una lista de control de acceso en “Applications/Utilities” que no se esperaba.
Se ha encontrado una lista de control de acceso en “Applications” que no se esperaba.
Se ha encontrado una lista de control de acceso en “Library” que no se esperaba.
Se ha encontrado una lista de control de acceso en “System/Library/User Template/Spanish.lproj/Sites” que no se esperaba.
Se ha encontrado una lista de control de acceso en “System/Library/User Template/Spanish.lproj/Desktop” que no se esperaba.
Se ha encontrado una lista de control de acceso en “System/Library/User Template/Spanish.lproj/Documents” que no se esperaba.
and so on...
The translation is "It was found an acces control list in "Applications/Utilities" that wasn't expected" etc...
And I still have that extrange little icon over User Templates folder on "System/Library/UserTemplates"
I don't have installed any other program else on my computer than logic and leopard! I don't know what the "h.." is going on with this "f.." logic program!
SO PLEASE IF ANYONE KNOWS HOW TO SOLVE THIS OR ANY KIND OF HELP WOULD BE APPRECIATED!
THANK YOU.
Sorry about the length of the post and my english.

Thanks a lot for your response Scott, I really appreciate it.
I have downloaded the 7.4 protools, but not installed because the 7.3 software cause instalations errors on the computer and the digi is not recognized.
Anyway I wanted to start familiarizing with Logic 8. I thought because Logic and Mac are from Apple they would be totally compatible...and of course they are not!
In other hands I spent 6,300 dollards in new equipment to avoid this kind of problems...but at the end you get all the same traubles whatever you buy or not (crack) the things...so.
Anyway, now my computer it seem to be damage... the fan never stop and I am geting some wierd icons over some folders (stop icons) so...
By the way, I bought everything in SweetWater if anyone wants to know, and so far they seems to be only available to put their hands to get the money but they are always too bussy to help and solve all this crap they did to me.
I bought logic studio, mac pro 8-core 3.0 and digi 003 to them...any of these are working!!! nice!!! and after one waste month they didn't give me any other solution besides to wait and wait and wait days and days in order to talk to any of the technicians...It seems their technicians only have time to ensembly equipment to sell it as soon as they can...nice!!!
