Error -44085 means "The FPGA bitfile has an incorrect version or revision". Meaning, the version of software on your PC does not match what is on your cRIO. Most likely you need to run the imaging tool to update your cRIO. The other possibility is if you are developing code on multiple machines, your cRIO could be up to date (imaged from an up to date PC) but you are using a system without the latest updates applied.

Generally, you can learn about an error code in LabVIEW by clicking Help->Explain Error... However, error codes in the -44000 to -44099 range are FRC specific, and the publicly released software in update 1 and 2 does not contain documentation for these errors. Update 3 will include explanations for FRC specific errors.
