Theres a workaround for version conflict. Try to install for example spanish language version of 1.0 and russian (if ur virus protection is up to date)language version 2.0. That should guarantee collision avoidance over communication channel and thus remove the I/O port bug. They should work independently rather fine. However u shouldnt try running both applications simultaneously that might introduce some unwanted noise issues.
Also try to install language version which is gibberish to u self, that somehow seems to sandbox offending process and thus prevent it from interfering other processes and protecting their running privilidges.
If nothing else work u still have option to run both platforms on different boxes, but thats economically unfeasible for most of us...
Anyway im not best giving adivices... had to dump 3.0 after experiencing a DoS (Denial of service).
