rich.
this might not be an issue in your case , but ive seen many situations
on pc's where winky hard drives can cause a problem.
i dunno..mebe one of the sectors has gone pear shaped.
you mentioned your pc spec but didnt mention the hard drive used.
is this the only hard drive on your pc ??
if a hard drive is used for lots of different apps , sometimes it can take quite a beating.
so my questions are..
1. whats the make n model of the drive.
2. are you useing just one drive for OS and recording ??
(i normally recommend a dedicated drive for recording work for budget 7200 rpm with 32 mb cache
only 70 buks.drives with low cache like 2mb cache sometimes cause probs.)
3. is the drive in your pc , one that you put in from an older system ??
this can be problematic sometimes.
4. have you done a drive scan to ascertain any problematic sectors
or performance probs ?? also be aware sometimes win can revert to a slower pio mode
if it encounters problems. check in device mgr if dma is enabled.
5. how much free space on the drive ?? plenty of space ??

the reason i mention the above is ive seen various error msges in music software,
but the problem sometimes lies elsewhere.
and often ive found people always hammer away with various apps on one drive systems
without realising ovedr time drives can get problems.
the other aspect is ive seen people use any old clunky drive in a music app
situation , and then wonder why they get probs.

one thing i would like you to do also.
to assess your memory useage on your pc , and whether youy REALLY ARE
running out of memory.

please run this test.
before starting biab..bring up xp task manager
which shows memory useage against each process/task on your pc.
jot down how much real memory is being used .
(do you have lots of other apps running while runnning biab ??)
now start biab, and try to reproduce the outof memory error message.
when you get the error message...
note the memory useage that xp task manager is telling you.
this will give you clues in summary if something is really creating an out of
memory condition either in biab or outside biab.
in fact it would be nice to post a pic somewhere showing the win
task manager memory useage display.

the reason for mentioning the above is to alert you to the fact there are many possible causes
of probs. mebe it is a prob in biab , but it might be something else causeing the problem also.
are you by any chance running any other programs at the same time as biab that chew up lots of memory ?? are you on the net while running biab ?? any anti virus//security software
thats chewing up memory ??
just some things to think about. all the best.
