Sonar X2 Essential Freezing Up

I purchased Essentials last week and I'm having an issue with Cakewalk freezing up everytime I try to record.  So far I've only successfully recorded half of one song with bass, piano, synth and drums.  I'm trying to record another song and every single time I lay down any track Cakewalk freezed before anything is saved.  Below is my system:
 
Gateway SX2855
Intel Celeron G460 @ 1.80 GHz
4.00 GB RAM
64-Bit Operating System
 
I installed Essential 64 bit version. 
 
I would really appreciate any help you guys could give me.  I never had this issue with Reaper, but Reaper was a pain to use with VST.  Essential is a far superior product but this freezing issue is really getting frustrating.

hmm... I hate to say it but it might be time to upgrade your system.

However as kevo said try the Quickfix and if you haven't already done it you should take a close look at optimizing your system. In fact give Cakewalk tech support a call. They'll give you a bunch of suggestions.

In the meantime try turning up your latency buffers and freeze your tracks whenever possible to keep resource consumption down. Cheers.

  Ah... perhaps. I really gotta get around to installing that thing. Not doing much on the DAW at the moment anyway though. Just a couple of light projects. Gonna start looking at some old live sets and see what R-Mix can do for them. 

Thanks guys, adjusting the latency buffers (and running Malware to clean-up) seems to have solved the problem.  I was able to complete my bass parts and upload to dropbox for the guitarist to mix everything in.
