Did a search cannot see a resolution. Parallels Desktop 3.0 for Mac Build 5582 won't update despite activation and registration. On Mac Pro dual quad core 3Ghz, 8Gb RAM actual. !Gb allocated to parallels. Mac Tiger 10.4.11 (852167) Kernel Darwin 8.11.1 Registration and activation have been effective but it keeps asking me to register to download updates. Saw in search a recommendation to turn off auto updates but this did not change anything. Getting a bit frustrated with parallels problems. It ran fine for quite a while but now seems a bit flaky. Reinstalls do not help the problem.
