Illustrator cc 2014 can't save files

Question

Hi!
I Have a lot of problems with the Illustrator CC 2014. And it freaks me out. I have no idea how to reach Adobe. I've tried another Adobe forum but haven't heard anything.. I would appreciate some sort of help. Or if someone knows where to post the question?
1) First of all can't save files… I wish this could be the number one feature in a design app but apparently not..
I got   "unknown error " and all work spent is gone forever. This happens a lot.
2) also lagging problems. when moving graphics and zooming in illustrator. it is SO stressful.
I have Two computers, with the same problems.
Imac 27 " mid 2011
Processor 3,4 ghz intel core i7
16 GB 1333 Mhz DDR3
AMD Redeon HD 6970M 1024 MB
Osx X lion 10.7.5
Imac 27" Retina 5k late 2014
3,5 ghz intel core i5
32 GB 1600 mhz DDr3
AMD Radeon R9
OsX Yosemite 10.10.1

Nils Petter,
If no brighter suggestion comes up, you may try the list, see below.
Did you install fully on both computers (after upgrading the OS if relevant)?
The following is a general list of things you may try when the issue is not in a specific file, and when it is not caused by issues with opening a file from external media. You may have tried/done some of them already; 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
If possible/applicable, you should save current artwork first, of course.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to at least 5 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible), for CS3 - CC you may find the folder here:

5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall (ticking the box to delete the preferences), run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.
