How to get rid of Alibre Desing red cross error?

Allways after locking or switching users or if the system activates screen saver alibre has this strange red crosses - it have been documented on alibre forums but for now i don't have solution for it - maybe some one here knows one!

I have reinstalled Alibre, drivers, searched windows event errors -no prevail only solution for now (and it's not the best one) is to save the file to new location and reopen it - i say to new location as i found a lot of my old models are not opening after saving with error to the same file)
