hi, a bit of an odd ball this one but perhapse someone may have some ideas.. I have a licenced copy of nero OEM suit with nero Express 6 and INCD4. Recently i had troubles with burning a duel layer data disk (not sure why possibly installing the XP Service Pack 2) so after checking the hardware i re-installed my OEM suit. The disk burned beautifuly but my computer is suffering serious lag and cant run Cubase (my most used and expensive program)properly. Unistalling the OEM suit has not resolved this so now im at a loss. My idea is to reinstall cubase, hopefully kicking it back to life but i dont know what to do about nero. what do you think? i know my 150gb hard drive is down to 20gb free space which may be causing issues. could this situation be doing all this? i have tryed more recent version of nero that have got to the burn stage and stopped. should i try some differnt software. i am exhausted from installing different versions of nero but this new development of cubase has got me worried!! Thanks so much for any advice you could give.
