What are the System Requirements to install Disk Accelerator Pro? When trying to install the software, I receive an error message stating: "_isNNAA.tmp has encountered a problem" (the NN would be a number and the AA would be a letter) The number and letter is different each time I try to install it. How do I install the software? When starting Disk Accelerator Pro, I receive the following error message: "Network error or warning occurred. Connection Error. The connection to Disk Accelerator Pro Agent could not be established. Possibly, the Disk Accelerator service has not been started. You can start it manually using the Window Services Management. No connection could be made because the target machine actively refused it. (10061)" How do I correct this? Can I restore deleted files after a defragmentation? How do I ensure that a defragmentation job only runs when my notebook computer is connected to a power source and not when it is operating on battery power? When I start Disk Accelerator Pro, my firewall tells me that someone is trying to access my hard drive. How can I solve this problem? Which defragmentation method is the right one for me?   Back To Top   If you still have further questions, please click here.
