VL.CoreLib.vl not compiling?

Just downloaded a fresh vvvvbeta42. Installed in C:/vvvv. Opened, it opened. When cloning a Template node VL or also when opening a file that includes a VL node, it gets stucked forever (30 mins so far).
Any insights? Thanks

ok working,
Just by deleting the whole beta_X64 folder C:\Users\XXXX\AppData\Local\vvvv and restart everything.
