can not start frame 11

dear all

i don't know what is wrong with my frame 11. until yesterday i had frame 10, 11 and 12 installed parallel on my win7 x64 machine. all of a sudden the creative cloud thingy came up and prompted me to login, etc. after that frame 10-12 didn't work anymore. i received the cryptic internal errors. happend already couple of times, i then ran the installers again and frame 10 & 12 worked after that. only frame 11 is still not functioning. i can start it, select wether structured or unstructred and that's it. it pops up quickly in the taskmanager but then disappears. latest updates are applied. deleting local maker.ini just brings the dialogue again. no effect after i made a decision. frame 11 refuses to start.

i then deleted all frames and cleansed the registry by hand (i know what i am doing!), tried to reinstall just frame 11 - no success.

now i start to wonder if my installer is corrupt somehow. can not find frame 11 or TCS4 anywhere to download. it's all gone.

any clues or hints are highly appreciated.

thanks.

chris.
