Hi Joni,
It seems that there was some slight misunderstanding (it's mostly my fault, sorry about that!
)
What I meant by "memory" last time was your RAM (random access memory) -- from your last report we found that you only had 200 free of your 1024mb.
However, since your LR seems to be working fine now after installing a new codec pack, then you need not worry about this issue anymore.
It would still be better if you had more RAM, though. So if you do plan to upgrade your system soon, then that would definitely be a great help to ensuring that LR works efficiently for you!
