Also I could create a new Visual class, the following error's reported inside the ".log". Before this happens, I used to solve a problem of "IWAV0168E", which had been commonly reported. The process was like "delete the error log -> clean and rebuild the project".</b>

First, is this a pre 1.2M2 VE driver? If so, we had a cache race
condition which caused the cache to go bad and produce this error. We've
fixed that with 1.2M2 so it shouldn't occur as much.
The steps to clear the cache are:
1) Open a Ve and then close it. Have no other VE's open.
2) Do Project->Clean...->Clean All. Wait for build to finish
3) Open your VE. It should now be ok.
