Quartus II is NOT stable itself

Im finding this QuartusII absolutely nightmarish !! Sent bugs report and told the version Id loaded two days prior was replaced by next SPack which solved the problem of editing ports in symbol editor.... also no simple tutorials showing how I get bus ports onto blocks .... Im taking over a QII6 design and the tutorials all seem too advanced or something like do you always need symbol file ? full of marketing crap and no substance ...if I use a block and I/O tables only can I avoid using symbol files ?

Can anyone help ? ... How do I terminate lines/busses in a shematic bdf file ....IM using the same assignations ie Temp_q[7..0] both in and outside the block but the compiler says no ports exist !!! :confused:
