Cannot save drawing-cannot open drawing

Recently downloaded Sketchup Pro 2015. Used a couple days and begin saving very slowly. Finally just got to where the save just kept running and never did finish. Started trying to open saved files and this started running forever. Anybody see this happening? Removed Sketchup 2015 and reloaded. No change. Have 1-1/2 weeks work at risk. Thanks,
