Bridge CS5 freezes after error message...."The operation could not be completed, there is not....

Error - The operation could not be completed.  Not enough storage is available to complete this operation.

After this happens I have to close Bridge as it is unresponsive to any further commands and I often I have to use the task manager to close it.

I have scoured these boards and the web for a solution and have found others w/ the same problem (even people w/ much more RAM) but have not found a solution beyond the usual advice of changing cache settings, increasing page file, or making sure there is enough hard drive space.

I have two 1TB hdd's w/ over 80% free space on each but I only have 2 GB RAM (all my old motherboard can handle).  However, this error message occurs even when Photoshop is not running (only Bridge) and my RAM usage meter shows that I still have plenty of unused RAM available.  I did not have this problem w/ Bridge CS4. The error msg. of not enough storage doesn't make since considering the available RAM showing and ample space on the hard disk assigned to the cache (which is a different physical drive than my OS or the Bridge program.)

Here are some of the things I have tried:

reset Bridge preferences at startup, changed the location of the Bridge cache, its size and options, purged the cache, changed the page file size on both drives to the max, defragmented drives, disabled Norton anti-virus, etc.

-What else can I try?

-Would creating a new partition on my 2nd hdd to be used solely for the Bridge cache make any difference and if so, why?

Please help, I am willing to try anything to get this to work.  It is a personal challenge at this point.... and I am determined to get Bridge CS5 to work on my machine...... 

Thanks in advance for any advice or insturctions you may offer!
