Project opening Bug nightmare ! Please help....Job at hand waiting...!

Hello I am doing a commercial of 30 sec. and my basic mixing is done...In Reaper + Reason rewire So I exported the Mix and Started Mastering in Samplitude.... But when I realize certain things need to be corrected in Mixing, I go back to Reaper, the original file does not open !!! What should I do ? It hangs, Reason window says - Engine not Responding Check your Rewire host. Reaper window hangs.... Yesterday same thing happened, but I opened the Backup file and it was ok.....But today even backup file is hanging....I am so stuck...Please help me.... I have a deadline...!

Have you tried opening with FX offline? Hold Ctrl Shift while opening ... might help ...

Thanks Nicholas....will try it and reply back....I hope it works man...

It opens like that....Thank god !!! But how to gain back all those FX ? How to make Invert FX OFFLINE mode ?

Glad you got it going ... now File, Save As to new name to make a safe copy, yes, before you do anything else? ;)

Fill us all in - how did you fix it?
