that sounds like a system error, I'd try running a defrag on your system. This usually tries to fix any linked / cross linked files or at least tries to remove any system errors to prevent it from happening again. I'd also try to reach tech support to double check that the way cta is installed in your system isn't causing it. i've never experienced problems like that from ic5 or cta, but i have experienced the system doing that with any program thats up at the time. I'd also run a scan for viruses as well, a virus or a malfunctioning TSR program will cause errors like this as well.....(TSR, the programs you have running in the background )
if you are an intermediate level user, you could try this as well....disclaimer.. use with caution, and at your own risk....this works for my system, but not all systems are alike...
2 softwares I use to maintain my computer are ccleaner ...it cleans out garbage files and potential registry issues http://www.piriform.com/ccleaner
and malwarebytes to scan for malware / viruses etc.. http://www.malwarebytes.org/
both programs have free versions.
