Had the very same problem.
I you take a look at the save game files (*.blk), then You`ll see that You have 99999 or so, of some artefacts(parts). Artefacts are skill symbol parts.
I Just started anew and the problem hasn`t occured once since that.
OR You can try to *FIX* the save game by editing your inventory.
These are the lines, that were messed in my save game file and you could edit:
girlModel:i=0(was 99999, set to:0)
partsCollected0:i=(0-2)
partsCollected1:i=(0-2)
partsCollected2:i=(0-2) //Don`t use 3 or more, I haven`t tried that yet, but I guess that it`ll just mess-up some trigger, that triggers skill advancement.
I think that the problem lies with the CH trainer `cause now I haven`t bought even one powerup bottle and I`m ok.

Thanks for the reply. Changing the values to the same as you had didn't work for me, though thanks for the suggestion. I had previously tried uninstalling and deleting all saves,settings and profiles without any luck. The only way i can get it to work is if i used the profile.blk that someone in the trainer thread posted. Not sure what's going on but i no longer have a settings.blk file but all is working fine so i'm not going to mess any more
